What is the strongest iron - Metals and their processing

The most durable metal. High strength metals:

Today we will look at the strongest metals in the world and discuss their properties. And titanium opens the “strength rating”.

Not the most durable?

The name of the metal presumably comes from the name of the ancient Greek hero Titan. Therefore, we associate this metal with indestructibility. Many consider titanium to be the strongest metal in the world. However, in reality this is far from the case.

Pure titanium was first obtained in 1925. The new material immediately attracted attention due to a number of properties. Titanium has begun to be very actively used in the industrial sector. Today, titanium is in 10th place among natural metals in terms of prevalence. The earth's crust contains about 700 million tons. That is, the current raw materials will last for another 150 years.

Titanium has excellent properties. It is a lightweight and durable metal that is resistant to corrosion. It can be easily heat treated and has a wide range of applications. It interacts with other elements of the periodic table only when heated. Found naturally in rutile and ilmenite ores.

Pure titanium is obtained by sintering ore with chlorine.

It is able to withstand enormous loads. The metal is distinguished by its high strength and impact resistance. It is used in the manufacture of vehicles, missiles and even submarines. Titanium can withstand pressure even at great depths.

It is also popular in the medical industry. Prostheses based on it do not interact with body tissues and are not subject to corrosion. But over the years it begins to wear out, which forces you to replace the prosthesis with a new one.

New developments

In 2016, scientists found a way to improve the properties of titanium and make it even more durable. The main goal of the research is to find a more durable material that is compatible with body tissues. And then we remembered gold, which has been used in prosthetics for many years.

The alloy of titanium and gold, after several attempts to find the ideal ratio of components, turned out to be incredibly durable. 4 times stronger than other metals used today for prosthetics.

Tantalum

One of the strongest metals. Named after the ancient Greek god Tantalus, who angered Zeus and was cast into hell. It has a silvery-white color with a bluish tint. It is a characteristic element of granitic and alkaline magma. It is extracted from the mineral coltan, the largest deposits of which are located in Brazil and Africa.

It was opened back in 1802. Then it was considered a variety of columbium, but later it was established that these are two different metals with similar properties. Only 100 years later it was possible to obtain pure tantalum. Its cost today is quite high - $150 per 1 kg of metal.

Tantalum is a refractory metal with a fairly high density.

From a chemical point of view, it is stable because it does not dissolve in dilute acids. In powder form, tantalum burns well in air. Used for the manufacture of electrolytic capacitors, heaters in vacuum furnaces. Tantalum capacitors increase the service life of electronic systems to 10-12 years.

It is noteworthy that even jewelers have found use for it - they replace platinum.

Strength testing of metals showed that the alloy of tantalum and tungsten has almost one hundred percent strength.

Osmium is the very best

Osmium is another incredibly strong metal. It is also included in the list of the rarest and most expensive. It is present in the earth's crust in minute quantities. It is classified as dispersed, that is, it does not have its own deposits. Therefore, its extraction is accompanied by enormous difficulties.

Osmium belongs to the group of platinum metals. Its cost is about $10,000 per gram. In price it is second only to artificial Californian. It consists of several isotopes that are incredibly difficult to separate. The most popular isotope is osmium-187.

Its price per gram reaches up to $200,000!

Osmium is the record holder for density among metals. In addition, it is a high-strength metal. Alloys containing osmium become resistant to corrosion and become stronger and more durable.

Metal is also used in its pure form, for example, to make expensive fountain pens, which practically do not wear out and write for years.

Chromium

Chromium, cobalt and tungsten have been known to science since 1913 and are united under the common name - stellites. They remain hard even at temperatures of 600 degrees Celsius.

This metal is mainly found in the deep layers of the Earth. It is also found in stony meteorites, which are considered analogues of our mantle. Only chrome spinels are of industrial value. Many minerals that contain chromium are completely useless. The purest chromium is obtained by electrolysis of concentrated aqueous solutions or electrolysis of chromium sulfate.

Metal in combination with steel significantly enhances its strength and also adds resistance to oxidation. It improves the characteristics of steel without reducing its ductility.

Ruthenium

It belongs to the platinum group and is classified as a noble metal. However, from their list, ruthenium is considered the least noble. It was discovered by the scientist Karl-Ernst Klaus in 1844. It is noteworthy that the professor constantly smelled and tasted the results of his research. Once he even received a burn to his mouth when he tasted one of the ruthenium compounds he discovered.

Its world reserves today are about 5,000 tons. Ruthenium has been studied for a long time, but many of its properties are still unknown. The problem is that no way has yet been found to completely purify ruthenium.

The contamination of raw materials prevents the study of its properties. However, doctors are confident that the use of metal in everyday life can increase the incidence of illness among the population. That is why the release of the ruthenium-106 isotope in the Urals caused such a resonance in the press.

After all, ruthenium-106 has radioactive properties.

At the same time, its value in 2017 unexpectedly surpassed all platinum metals.

Iridium is the strongest metal

It is iridium that has the highest strength. Yes, it is inferior to osmium in density, but has the highest strength coefficient. It is also called the rarest of metals, but in fact the content of astatine in the earth's crust is even lower.

Iridium was studied very carefully. 70 years later, its main properties - incredible strength and corrosion resistance - have become known throughout the world. Today it is used in many industries. The lion's share of the metal is exploited by the chemical industry. The remainder is distributed among many other areas, including medicine and jewelry. Iridium combined with platinum creates high-quality and very durable jewelry.

The strongest metal in the world

People began to use metal back in ancient times. The most accessible metal in nature and amenable to processing is copper. Copper products in the form of household utensils are found by archaeologists during excavations of ancient settlements. As technological progress grew, man learned to make alloys from various metals, which were useful to him in the manufacture of household items and weapons. This is how the strongest metal in the world appeared.

This unusually beautiful silver-white metal was discovered almost simultaneously at the end of the 18th century by two scientists - the Englishman W. Gregory and the German M. Klaproth. According to one version, titanium got its name in honor of the characters of ancient Greek myths, the mighty Titans; according to another, from Titania, the fairy queen from German mythology, because of its lightness. However, no use was found for it then.

Then in 1925, physicists in Holland were able to isolate pure titanium and discovered its many benefits. These are high indicators of manufacturability, specific strength and resistance to corrosion, very high strength at high temperatures. It also has high anti-corrosion resistance. These fantastic performance immediately attracted engineers and designers.

In 1940, the scientist Krol obtained pure titanium using the magnesium-thermal method, and since then this method has been the main one. The strongest metal on earth is mined in many places in the world - Russia, Ukraine, China, South Africa and others.

Titanium is twice as strong as iron in mechanical terms, and six times stronger than aluminum. Titanium alloys are currently the strongest in the world, and therefore have found application in the military (submarine, missile construction), shipbuilding and aviation industries (on supersonic aircraft).

This metal is also incredibly malleable, so it can be made into any shape - sheets, pipes, wire, tape. Titanium is widely used for the manufacture of medical prostheses (and it is biologically ideally compatible with the tissues of the human body), jewelry, sports equipment, etc.

It is also used in chemical production due to its anti-corrosion properties; this metal does not corrode in an aggressive environment. So, for testing purposes, a titanium plate was placed in sea water, and after 10 years it did not even rust!

Due to its high electrical resistance and non-magnetizing properties, it is widely used in radio electronics, for example, in structural parts of mobile phones. The use of titanium in the field of dentistry is very promising; its ability to fuse with human bone tissue is especially important, which gives strength and solidity in prosthetics. It is widely used in the manufacture of medical instruments.

Uranus

The natural oxidizing properties of uranium were used in antiquity (1st century BC) in the production of yellow glaze in ceramic products. One of the most well-known durable metals in world practice, it is weakly radioactive and is used in the production of nuclear fuel. The 20th century was even called the “age of Uranus.” This metal has paramagnetic properties.

Uranium is 2.5 times heavier than iron, forms many chemical compounds; its alloys with elements such as tin, lead, aluminum, mercury, and iron are used in production.

Tungsten

This is not only the strongest metal in the world, but also a very rare one, which is not even mined anywhere, but was obtained chemically back in 1781 in Sweden. The most temperature-resistant metal in the world. Due to its high refractoriness, it lends itself well to forging, and it can be pulled into a thin thread.

Its best known use is as tungsten filament in light bulbs. Widely used for the production of special instruments (incisors, cutters, surgical) and in jewelry production. Due to its property of not transmitting radioactive rays, it is used to produce containers for storing nuclear waste. Tungsten deposits in Russia are located in Altai, Chukotka, and the North Caucasus.

Rhenium

It got its name in Germany (Rhine River), where it was discovered in 1925; the metal itself is white. It is mined both in its pure form (Kuril Islands) and during the extraction of molybdenum and copper raw materials, but in very small quantities.

The strongest metal on earth is very hard and dense and melts well. Strength is high and does not depend on temperature changes, the disadvantage is high cost, toxic to humans. Used in electronics and aviation industries.

Osmium

The heaviest element, for example, a kilogram of osmium, looks like a ball that easily fits in your hand. It belongs to the platinum group of metals and is several times more expensive than gold. It got its name because of the bad smell during a chemical reaction carried out by the English scientist S. Tennant in 1803.

Externally it looks very beautiful: shiny silver crystals with a blue and cyan tint. It is usually used as an additive to other metals in industry (high-strength ceramic-metal cutters, medical knife blades). Its non-magnetic and durable properties are used in the manufacture of high-precision instruments.

Beryllium

It was obtained by chemist Paul Lebeau at the end of the 19th century. At first, this metal was nicknamed “sweet” because of its candy-like taste. Then it turned out that it has other attractive and original properties, for example, it does not want to enter into any chemical reactions with other elements with rare exceptions (halogen).

The strongest metal in the world is at the same time hard, brittle, light, and also highly toxic. Its exceptional strength (for example, a wire with a diameter of 1 mm can support the weight of a person) is used in laser and space technology, and nuclear energy.

New discoveries

We can go on and on about very strong metals, but technical progress is moving forward. Scientists from California recently announced to the world the emergence of a “liquid metal” (from the word “liquid”), which is stronger than titanium. In addition, it turned out to be super lightweight, flexible and highly durable. Therefore, scientists will have to create and develop ways to use the new metal, and in the future, perhaps, make many more discoveries.

TOP 10 most durable metals in the world

Metal is a material that is typically highly durable, shiny, and easy to change shape. Generally, all metals have good electrical conductivity. But not all metals are alike. That is why they are used for different purposes depending on the task at hand. In the periodic table of Mendeleev, 91 of the 118 elements are considered metals, but not all of them have sufficient strength.

What makes metal strong?

The strength of the metal depends on the following properties:

1. Tensile strength: how well the metal resists being stretched;

2. Compressive strength: how well the metal can withstand compression;

3. Yield Strength: How well a rod or beam of a particular metal resists bending and permanent damage;

4. Impact resistance: the ability to resist breaking when colliding with another object or surface.

The strongest metals

No. 1: Tungsten - production of bullets and missiles;

No. 2: Steel - construction of railways, roads and other infrastructure;

No. 3: Chrome - stainless steel production;

No. 4: Titanium - used in the aerospace industry as a lightweight yet durable metal;

What is the strongest metal in the world - TOP 5 elements

Metals include substances that have specific properties characteristic of them. In this case, high ductility and malleability, as well as electrical conductivity and a number of other parameters are taken into account. Which of them is the strongest metal in the world can be found out from the data below.

About metals in nature

The word “metal” came into Russian from German. Since the 16th century it has been found in books, although quite rarely. Later, in the era of Peter I, it began to be used more often, and then the word had the general meaning of “ore, mineral, metal.” And only during the period of M.V.’s activity. Lomonosov these concepts were differentiated.

In nature, metals are found quite rarely in their pure form. Basically, they are part of various ores, and also form various compounds, such as sulfides, oxides, carbonates and others.

In order to obtain pure metals, and this is very important for their future use, they need to be isolated and then purified. If necessary, metals are alloyed - special impurities are added in order to change their properties.

Currently, there is a division into ferrous metal ores, which include iron, and non-ferrous ores. Precious or noble metals include gold, platinum and silver.

There are metals even in the human body. Calcium, sodium, magnesium, copper, iron - this is a list of these substances that are found in the greatest quantities.

How are metals produced?

Metal-containing ores are considered the source of these most necessary substances for all modern humanity. To find out their exact location, certain search methods are used, which are based on exploration and study of deposits. Metals are obtained as follows:

Ore deposits are developed by open-pit or quarry, as well as underground or mine. Combined methods are possible.
Ore beneficiation is the separation of useful components from raw materials, so-called ore concentrates.
Extraction of metals from enriched ores by chemical or electrolytic reduction using high temperatures or aqueous chemistry.
Most often, metals are smelted, the ore and a reducing agent are heated to very high temperatures. For iron, carbon is usually used.

Depending on their further use, metals are divided into groups:

Construction materials. Both the metals themselves and their alloys with significantly improved properties are used. In this case, strength, impermeability to liquids and gases, and homogeneity are valued.
Materials for tools, most often referring to the working part. Tool steels and hard alloys are suitable for this purpose.
Electrical materials. Such metals are used as good conductors of electricity. The most common of them are copper and aluminum. They are also used as materials with high resistance - nichrome and others.

The strongest of metals

The strength of metals is their ability to resist destruction under the influence of internal stresses, which can arise when external forces influence these materials. This is also the property of a structure to maintain its characteristics for a certain time.

Many alloys are quite strong and resistant not only to physical but also chemical influences; they are not pure metals. There are metals that can be called the most durable.

Titanium, which melts at a temperature above 1,941 K (1660±20 °C), uranium, which is a radioactive metal, refractory tungsten, which boils at a temperature of at least 5,828 K (5555 °C). As well as others that have unique properties and are necessary in the process of manufacturing parts, tools and objects using the most modern technologies.

The five most durable of them include metals whose properties are already known; they are widely used in various sectors of the national economy and are used in scientific experiments and developments.

5. Rhenium

Found in molybdenum ores and copper raw materials. Has high hardness and density. Very refractory. Its strength cannot be reduced even under the influence of critical temperature changes. Widely used in many electronic devices and technical means.

4. Beryllium

A rare-earth metal with a silver-gray tint and shiny, crystalline formations when broken. Interestingly, beryllium crystals taste somewhat sweet, which is why it was originally called “glucinium,” which means “sweet.”

Thanks to this metal, a new technology has emerged, which is used in the synthesis of artificial stones - emeralds, aquamarines, for the needs of the jewelry industry. Beryllium was discovered while studying the properties of beryl, a semi-precious stone. In 1828, the German scientist F. Wöller obtained metallic beryllium.

It does not interact with x-rays, therefore, it is actively used to create special devices. In addition, beryllium alloys are used in the manufacture of neutron reflectors and moderators for installation in a nuclear reactor.

Its fire-resistant and anti-corrosion properties, high thermal conductivity make it an indispensable element for creating alloys used in aircraft construction and the aerospace industry.

3. Chrome

This metal was discovered in the Middle Urals. M.V. wrote about him. Lomonosov in his work “The First Foundations of Metallurgy” in 1763. It is very widespread, its most famous and extensive deposits are located in South Africa, Kazakhstan and Russia (Urals). of this metal in ores fluctuates greatly.

Its color is light blue, with a tint. In its pure form it is very hard and can be processed quite well. It serves as an important component for the creation of alloy steels, especially stainless steels, used in the electroplating and aerospace industries.

Its alloy with iron, ferrochrome, is necessary for the production of metal-cutting tools.

2. Tantalum

This metal is considered valuable, since its properties are only slightly lower than those of noble metals. It has strong resistance to various acids and is not susceptible to corrosion.

Tantalum is used in various designs and compounds, for the manufacture of products of complex shapes and as a basis for the production of acetic and phosphoric acids. The metal is used in medicine because it can be combined with human tissue.

The rocket industry needs the heat-resistant alloy of tantalum and tungsten because it can withstand temperatures of 2,500 °C. Tantalum capacitors are installed on radar devices and used in electronic systems as transmitters.

1. Iridium

Iridium is considered one of the strongest metals in the world. The metal is silver in color and very hard. It is classified as a platinum group metal. It is difficult to process and, moreover, refractory. Iridium practically does not interact with caustic substances.

It is used in many industries. Including in jewelry, medical and chemical industries. Significantly improves the resistance of tungsten, chromium and titanium compounds to acidic environments.

Pure iridium is not a toxic material, but its individual compounds can be poisonous.

Despite the fact that many metals have decent characteristics, it is quite difficult to pinpoint exactly which is the strongest metal in the world. To do this, all their parameters are studied in accordance with various analytical systems. But at present, all scientists claim that iridium confidently occupies first place in terms of strength.

The hardest steel in the world

Do you know which material on our planet is considered the strongest? We all know from school that diamond is the strongest mineral, but it is far from the strongest. Hardness is not the main property that characterizes matter. Some properties may prevent scratches, while others may promote elasticity. Want to know more? Here is a rating of materials that will be very difficult to destroy.

Diamond

Diamond in all its glory

A classic example of strength, stuck in textbooks and heads. Its hardness means it is scratch resistant. On the Mohs scale (a qualitative scale that measures the resistance of various minerals), diamond scores at 10 (the scale goes from 1 to 10, with 10 being the hardest substance). Diamond is so hard that other diamonds must be used to cut it.

Darwin's spider silk

A web that can stop an airbus

Often cited as the world's most complex biological substance (though this claim is now disputed by its inventors), Darwin's web is stronger than steel and has greater stiffness than Kevlar. Its weight is no less remarkable: a thread long enough to encircle the Earth weighs only 0.5 kg.

Aerographite

Aerographite in a regular package

This synthetic foam is one of the lightest building materials in the world. Aerographite is about 75 times lighter than polystyrene foam (but much stronger!). This material can be compressed to 30 times its original size without damaging its structure. Another interesting point: aerographite can support 40,000 times its own weight.

Palladium micro-doped glass

Glass during a crash test

This substance was developed by scientists in California. Microalloy glass has an almost perfect combination of rigidity and strength. The reason for this is that its chemical structure reduces the brittleness of glass, but retains the rigidity of palladium.

Wolfram carbide

Tungsten drill

Tungsten carbide is incredibly hard and has qualitatively high rigidity, but it is quite brittle and can be bent easily.

Silicon carbide

Silicon carbide in the form of crystals

This material is used to create armor for battle tanks. In fact, it is used in almost anything that can protect against bullets. It has a Mohs hardness rating of 9 and also has low thermal expansion.

Cubic boron nitride

Molecular structure of boron nitride

About as strong as diamond, cubic boron nitride has one important advantage: it is insoluble in nickel and iron at high temperatures. For this reason, it can be used to process these elements (diamond forms of nitrides with iron and nickel at high temperatures).

Dyneema

Dyneema cable

Considered the strongest fiber in the world. You might be surprised by this fact: Dainima is lighter than water, but it can stop bullets!

Titanium alloys

Alloy tube

Titanium alloys are extremely flexible and have very high tensile strength, but do not have the same rigidity as steel alloys.

Amorphous alloys

Amorphous metals change shape easily

Liquidmetal was developed by Caltech. Despite the name, this metal is not liquid and at room temperature has a high level of strength and wear resistance. When heated, amorphous alloys can change shape.

Nanocellulose

Future paper could be harder than diamonds

This latest invention is created from wood pulp, while having a greater degree of strength than steel! And much cheaper. Many scientists consider nanocellulose to be a cheap alternative to palladium glass and carbon fiber.

Shellfish teeth

saucer shell

We mentioned earlier that Darwin's spiders spin threads of some of the strongest organic material on Earth. Nevertheless, the limpet's teeth turned out to be even stronger than the webs. Limpet teeth are extremely tough.

The reason for these amazing characteristics is the purpose: collecting algae from the surface of rocks and corals.

Scientists believe that in the future we could copy the fibrous structure of limpet teeth and use it in the automobile industry, ships and even the aviation industry.

Maraging steels

A rocket stage in which many components contain maraging steels

This substance combines a high level of strength and rigidity without loss of elasticity. Steel alloys of this type are used in aerospace and industrial manufacturing technologies.

Kevlar

Kevlar helmet stopped a bullet

Used in everything from drums to bulletproof vests, Kevlar is synonymous with toughness. Kevlar is a type of plastic that has extremely high tensile strength. In fact, it is about 8 times larger than steel wire! It can also withstand temperatures around 450℃.

Spectra

Spectra pipes

High performance polyethylene is a truly durable plastic. This lightweight, strong thread can withstand incredible tension and is ten times stronger than steel. Similar to Kevlar, Spectra is also used for ballistic resistant vests, helmets and armored vehicles.

Graphene

Flexible graphene screen

A sheet of graphene (an allotrope of carbon) one atom thick is 200 times stronger than steel. Although graphene looks like cellophane, it is truly amazing. It would take a school bus balancing on a pencil to pierce a standard A1 sheet of this material!

Buckypaper

New technology that could revolutionize our understanding of strength

This nanotechnology is made from carbon tubes that are 50,000 times thinner than human hair. This explains why it is 10 times lighter than steel but 500 times stronger.

Metal microgrid

microlattice alloys are regularly used in satellites

The world's lightest metal, metal microlattice is also one of the lightest structural materials on Earth.

Some scientists claim that it is 100 times lighter than polystyrene foam! A porous but extremely strong material, it is used in many fields of technology.

Boeing has mentioned using it in aircraft, mainly in floors, seats and walls.

Carbon nanotubes

Nanotube model

Carbon nanotubes (CNTs) can be described as “seamless cylindrical hollow fibers” that consist of a single rolled molecular sheet of pure graphite. The result is a very light material. At the nanoscale, carbon nanotubes have 200 times the strength of steel.

Airbrush

Fantastic airbrush is hard to even describe!

Also known as graphene airgel. Imagine the strength of graphene combined with unimaginable lightness. Airgel is 7 times lighter than air! This incredible material can fully recover from over 90% compression and can absorb up to 900 times its weight in oil. It is hoped that this material can be used to clean up oil spills.

Unnamed substance under development at MIT

Massachusetts Polytechnic Main Building

At the time of this writing, scientists at MIT believe they have discovered the secret to maximizing the 2D strength of graphene in 3D. Their as-yet unnamed substance may have about 5% the density of steel, but 10 times the strength.

Carbin

Molecular structure of carbyne

Despite being a single chain of atoms, carbyne has twice the tensile strength of graphene and three times the stiffness of diamond.

Wurtzite boron nitride

birthplace of boron nitride

This natural substance is produced in the craters of active volcanoes and is 18% stronger than diamond. It is one of two naturally occurring substances currently found to be harder than diamonds. The problem is that there is not much of this substance, and now it is difficult to say for sure whether this statement is 100% true.

Lonsdaleite

Meteorites are the main sources of lonsdaleite

Also known as hexagonal diamond, this substance is made up of carbon atoms, but they are simply arranged differently.

Along with wurtzite boron nitride, it is one of two natural substances harder than diamond. In fact, Lonsdaleite is 58% harder! However, as with the previous substance, it is found in relatively small volumes.

Sometimes it occurs when graphite meteorites collide with planet Earth.

The future is just around the corner, so by the end of the 21st century we can expect the emergence of ultra-strong and ultra-light materials that will replace Kevlar and diamonds. In the meantime, one can only be amazed at the development of modern technologies.

Iridium

So, the strongest metal is iridium. It is obtained by precipitation from the dissolution of platinum in sulfuric acid. After the reaction, the substance becomes black, and later in the process of various compounds it can change color: hence the name, which means “rainbow”. Iridium was discovered in the early 19th century, and since then only two ways have been found to dissolve it: molten lye and sodium peroxide.

Iridium is very rare in nature; its amount in the earth does not exceed 1 in 1,000,000,000. As a result, one ounce of the material costs at least $1,000.

Iridium is widely used in various fields of human activity, especially in medicine. It is used to produce eye prostheses, hearing aids, electrodes for the brain, as well as special capsules that are implanted into cancer tumors.

According to scientists, such a small amount of matter indicates that it is of alien origin, namely, brought by some kind of asteroid.

What alloy is considered the strongest in the world?

Metals together with alloying additives form the strongest alloy. First of all, this concerns hardness. In addition, they differ in a number of indicators, including heat and electrical conductivity. Strong alloys are in demand in industry. This is especially true for aircraft construction, where lightness is required along with strength. The automotive and shipbuilding industries need strong alloys.

How metals are produced

Metals do not occur in nature in their pure form. They are contained in ores.

Their production proceeds in the following stages:

identification of deposits;
ore mining:
metal extraction.

The most durable alloy

The hardest alloys in the world are tungsten. The basis is powders consisting of several metal carbides and cobalt. Mixing is carried out in a certain proportion. The technology developed by scientists makes it possible to obtain alloys with a high degree of hardness.

Such compounds are marked with the letter designation: VK3, where B is the tungsten group. K is the cobalt content in percent.

10 Strongest Metals in the World

When people talk about the strongest metals in the world , one immediately thinks of a medieval knight with a sword at the ready and in armor made of the legendary Damascus steel.

It is this that many rightly consider to be the hardest, most durable, resistant to mechanical or chemical influences. But steel is not pure metal; it consists of several components that have been processed to change the final properties of the finished product.

Consequently, it cannot be called a substance with the highest hardness. What metal is the strongest on the planet?

10Titanium

Titanium is in 10th position in our ranking of the strongest metals in the world. It is a high-strength, silver-colored, low-density solid.

Titanium is resistant to high temperatures, it does not corrode, is resistant to chemicals and is not afraid of mechanical damage. It is possible to melt titanium only at temperatures above 3200 degrees, and it boils when heated to a temperature of 3300 degrees.

The scope of application of this metal is wide and varied - from the military industry to medicine.

Titanium was discovered by English and German chemists in the 18th century, and they named it in honor of the Titans - giant mythical creatures with unprecedented strength and other supernatural abilities.

For a long time, titanium was not used for industrial purposes, since they could not bypass the natural fragility of this metal. It was possible to obtain it in its pure form only in the winter of 1925

9Uranus

Uranium takes 9th place in the Top 10. Its distinctive feature is weak radioactivity. Uranium occurs in nature both in pure form and as a component of sedimentary rocks. Among the main properties of this metal, it is necessary to highlight good flexibility and malleability, ductility, which allows it to be used in various industries.

Uranium alloys subjected to heat treatment are characterized by high resistance to corrosion; products made from them do not change shape due to temperature changes. That is why this metal was used to make tool steel until the mid-30s of the last century, but later this technology was abandoned.

8Tungsten

Tungsten is in 8th place in our ranking. This metal has amazing, unparalleled refractory properties. It boils at an incredibly high temperature - 5900 degrees.

And this hard silver-gray metal with a characteristic shine is not afraid of even the most aggressive chemicals, easily takes shape during the forging process and is able to stretch into the thinnest thread without breaking.

Tungsten filament - every person has heard and seen it. So this thread is made from tungsten.

From German, the word “tungsten” is translated as “wolf foam.”
The metal was discovered by the Swedish chemist Karl Scheele in 1781

7Renium

This silvery-white transition metal belongs to the expensive category, it is indispensable in the manufacturing process of modern electronics and technology.

Rhenium was awarded the title of one of the most durable metals in the world due to its hardness and density, which do not decrease even under the influence of temperature changes. Rhenium is refractory and is produced from molybdenum and copper ore.

This process is quite complex and labor-intensive, which explains the high cost of the finished metal. To obtain 1 kg of rhenium, 2 thousand tons of ore are needed; the finished production of this metal is no more than 40 tons per year.

Rhenium was invented by famous German chemists Ida and Walter Noddack, and they named it in honor of the picturesque Rhine River.

6Osmium

The 6th position in our rating is given to osmium, the strongest metal in the world, belonging to the platinum group and characterized by incredible density. By analogy with most platinum metals, osmium is refractory and hard, but at the same time it is fragile; is not afraid of mechanical damage and exposure to aggressive substances.

A distinctive feature of osmium is its silvery-white color with a barely noticeable bluish tint and a rather unpleasant odor (something reminiscent of a combination of garlic and bleach).

This metal is not found in its pure form in nature; very rarely it can be found in conjunction with iridium, and even then only in some areas of Siberia, Canada, the USA and South Africa. Osmium is scarce, so it is extremely expensive and is used only where the enormous investment in its extraction is justified.

This metal is used in electronics, the space and chemical industries, and surgery. It is the main component in the production of a rare drug - cortisone.

Osmium is the most expensive metal in the world. The price for 1 gram can reach 200 thousand dollars.

5Beryllium

Beryllium has a light gray color and is characterized by hardness, fire resistance, good thermal conductivity and toxicity. The metal is mined from rocks and is widely used by modern science. It is indispensable in the aerospace industry and aviation, in nuclear energy and in metallurgy.

4Chrome

Chromium is the most common of the hardest metals in the world, products made from

which is sure to be found in every home. It is durable, resistant to aggressive environments, has a soft blue color and a characteristic shine.

Chromium is widely distributed in nature in the form of chromium iron ore, it is used in almost all industries, and is added to other metals to give them additional hardness, corrosion resistance and improve their appearance.

Chrome-plated parts of interior items, plumbing fixtures and household appliances become an excellent decoration for every home.

The melting point of chromium is 1907 degrees, it boils at a temperature of 2671 degrees. In its pure form, chromium is very viscous and viscous, but in combination with oxygen it becomes brittle and extremely hard.

3Tantalum

Tantalum is in 3rd place in our ranking; it is worthy of a “bronze medal” as one of the most durable metals on the planet. Tantalum has a silvery color with a characteristic lead-like luster, is characterized by increased hardness and amazing density.

Along with refractoriness, strength, resistance to rust and aggressive chemical attack, this metal is characterized by ductility. It is easily machined, which is highly valued in the chemical industry and metallurgy.

The metal is indispensable during the construction of nuclear reactors; it is the main element of heat-resistant alloys.

2Ruthenium

Ruthenium is silver in color and is characterized by a unique feature - the presence of fragments of muscle tissue of living beings. According to scientists, it was this unusual composition that influenced the properties of the metal and made it super-strong.

Ruthenium is not only strong and hard, it is also chemically stable, can form complex compounds and plays the role of a catalyst for chemical reactions. The properties of this metal described above make it indispensable in the manufacture of various wiring and contacts, and laboratory glassware. The metal is also in demand in jewelry.

As for the production of ruthenium itself, it is almost entirely concentrated in the Republic of South Africa.

1Iridium

Iridium was unanimously awarded the title of the strongest metal in the world - a refractory substance of unprecedented hardness. It is an extremely rare metal, not found in its pure form, but is sometimes mined in combination with osmium. Iridium is hard and therefore difficult to machine and is resistant to chemicals. It is used to impart additional oxidation resistance to chromium and titanium and is used in jewelry and many industries.
