Where can you find brass?

Methods for determining copper and brass yourself at home

Copper is a metal that, due to its characteristics, is suitable for making decorative items. Copper is also a component of metal alloys used for the same purpose. The most popular alloy is brass, which contains copper, as well as tin and zinc. Many people wonder how to distinguish copper from brass, because outwardly they are practically indistinguishable.

Copper and brass

Brass is characterized by the following composition: copper accounts for 70%, and zinc - 30%. As for the last component, 50% of the brass alloy is made from recycled zinc. Technical brass contains up to 50% of this zinc, and up to 4% of the alloy composition can be lead.

Product made of brass

How to test copper and brass?

If you know the fundamental differences between brass and copper, then the test can be carried out at home. What they do for this:

1. To distinguish brass from copper, you must first clean the item being tested from dirt. For this, a solution of vinegar and water is suitable, which you need to soak a cloth and wipe the product being tested. This product will remove not only dirt, but also oxides.
2. To identify copper and differentiate it from brass, you need to find a white light source. Copper is characterized by a uniform red-brown color, while brass has iridescence of several colors on its surface. The heterogeneous shade of brass is explained by the fact that the alloy consists of several metals, which determine its color. As for checking brass and copper under daylight or yellow lamp light, it will not be possible to evaluate the color of the metals in this way.
3. Copper is a soft metal that will produce a muffled sound when struck against a hard surface. Brass is characterized by a ringing and sharp sound when it hits the surface. It is advisable to apply this verification method to large items.
4. You need to take the product and carefully examine its surface, namely, check for any marks. Brass is an alloy, products from which are marked (this is the letter “L”). As for copper, in most cases there are no marks on products made from it. But if a marking is still found, you need to pay attention to it. In Russia, copper is marked with the letter “M”, followed by a code of numbers and letters, the decoding of which can be read in special reference books.
5. Copper may differ from brass in its area of ​​application. The first metal is rarely used in the manufacture of tools and spare parts. At the same time, copper is an ideal raw material for the manufacture of electrical wires, since the metal perfectly conducts electric current.

This is what copper looks like

How are metals not tested?

As for such a popular method of testing metals as a magnet, it is not suitable in the case of brass and copper. The thing is that both brass and copper are attracted to a magnet. Testing metals based on their flexibility will also not bring results, since copper and brass bend well.

How to identify brass at home - Metalworker's Guide

Anyone who searches for and sells non-ferrous metal sometimes has doubts about the type of scrap and, accordingly, its true value upon delivery.

Copper is a non-ferrous metal, and brass is an alloy that is typically 70% copper, so it often resembles it.

A mistake can be quite costly. For copper at collection points they give 285-300 rubles, for brass - about 150 . There are many ways to find out what kind of metal we see - copper or brass, and we will tell you how to distinguish them from each other in this article.

What is copper and brass

Copper is a non-ferrous metal. Its color is reddish-pink, it is pliable when working, soft and malleable. It has high thermal and electrical conductivity, so copper is often used to produce:

• parts of electrical appliances;
• cables;
• radiators.

Copper is not hardened because it becomes hard even after cold forging. It tends to become covered with patina - a green coating that occurs when the ambient humidity is high.

To increase strength, improve a number of other indicators and reduce the cost of the material, impurities are added and an alloy is obtained.

One such alloy is brass .

In the classic version it contains a third of zinc.

Brass is golden yellow, stronger and harder. It does not oxidize so intensively , and is not so plastic.

Sometimes, depending on the purpose of the alloy, they add:

• tin;
• silicon;
• lead;
• manganese.

Similarities and differences

Brass alloy consists mostly of copper, so it is natural that they are similar not only visually, but also in some properties. The more copper in the alloy, the more similar their colors will be. This is where the exact coincidences end.

Visually, less than 80% copper are easily distinguished . They are slightly similar to gold, as they have a pronounced yellow tint. The more zinc, the lighter the shade.

Because of this, brass is even used to counterfeit or imitate gold . Copper has a main shade of reddish, which often has a pink tint.

With a strong decrease in temperature, brass does not lose its relatively limited ductility and does not become brittle . Conducts electricity and heat worse.

They differ in such a way as hardness .

Copper is softer and more ductile , while brass, on the contrary, is hard and it is difficult to give it any shape without annealing.

The shavings are also different: for brass they are needle- shaped , for copper they are twisted into a spiral .

Let's look at the properties that brass and copper have and whether they have any differences:

Copper	Brass
Plastic, soft	Solid
Reddish-brown-pink tint	Golden tone
Lower sound on impact	Alt
Heavy	Easier
The shavings are twisted into a spiral	Needle shavings

Most often you can distinguish by:

• mind;
• weight;
• degree of hardness

without the use of any tools or equipment.

But there are situations when, for accuracy, it is necessary to use :

• reagents,
• tools,
• devices.

Before assessing the scrap that you are going to take to the collection point, you need to clean it of dirt, otherwise you won’t be able to accurately determine it by eye.

Both metals, although to varying degrees, can develop a patina .

Therefore, do not forget to clean the scrap well.

If an object has been in the open air or in water for a long time, the patina layer is difficult to remove.

Sometimes it will be justified to purchase a special cleaning product .

It is advisable to inspect the scrap under a powerful white light.

This implies that one can view either under the sun on a fine day or under a bright fluorescent lamp . Incandescent lamp is not suitable.

Pure copper will have a reddish-brown tint, sometimes with a pink tint. Keep in mind that brass can be red or orange. This type is commonly used for decorations and water pipes.

If the material has an orange, yellow or golden tint, you can be almost sure that it is brass.

Plumbing brass and what it is used with

Of course, no one will literally absorb brass, but this alloy has become so widely used in the food industry, as well as in the manufacture of sanitary fittings, the parts of which have direct contact with drinking water, that it would be reasonable to think about the hygienic characteristics of brass. This is exactly what we will do in today's article.

What is plumbing brass and what does it consist of?

Without resorting to cumbersome terms and multi-volume technical information, brass is an alloy consisting of two (copper and zinc) or more components (the so-called multi-component brass, which may include:

• aluminum and nickel;
• iron and manganese;
• tin;
• lead;
• silicon.

A pure two-component brass alloy has excellent physical properties, including high fluidity and ductility, making it possible to manufacture products of absolutely any shape. These qualities are indispensable for the production of sanitary fittings, especially faucets, which today can have the most incredible design and geometry.

If there are more components in the alloy, it means that brass has even higher physical and chemical characteristics, for example, adding iron to the alloy increases strength, etc. However, this does not always have a positive effect on hygienic indicators.

That’s why, when choosing a faucet or any other plumbing fittings, it is very important not to be cheap, otherwise, instead of a quality product, you may get a product that will not only quickly fail, but can also cause damage to your health.

Of course, the best solution would be spectral analysis - and this is the only true reliable method for determining the composition and suitability of a brass alloy - however, such measures are not available to everyone. You can protect yourself in other ways, but this requires the necessary minimum knowledge.

Why are plumbing fixtures made from plumbing brass?

In the manufacture of fittings and elements of heating systems (domestic), standard brass is used, which is resistant to corrosion. But for water supply systems, the requirements and standards for the material used are much higher. One of the international standards directly concerns the percentage of lead in drinking water, which should not be higher than 0.2%.

Cracking and corrosion processes in brass products used as sanitary fittings are unacceptable. Due to corrosion, the process of dezincification (also known as dezincification) of the brass begins. What is this and how does it threaten the product? Due to the leaching of zinc from brass, alloy components, including copper, begin to leak into the water, which worsens the hygienic characteristics of the water.

In turn, corrosion is more aggressive in water that has a high concentration of salts and lime impurities, as well as a low pH level.

It turns out to be a vicious circle: the lower the quality of the water supplied through the system, the more negatively this affects the condition of the fittings and, as a consequence, the water itself in the future. This is why all fittings and fixtures used in drinking water systems must comply with specific standards, such as DIN EN 1717-2001 (protection against contamination in drinking water installations and general requirements for devices to prevent backflow contamination).

How to choose a brass faucet?

So, what should you consider first when choosing a mixer? Manufacturer, price, purpose of the product and, of course, material. A good faucet is a product made of high-quality brass alloy (or stainless steel, but we’ll talk about that another time) with a durable coating.

The standard coating option is nickel-chrome, which has a characteristic gray-blue tint and a shiny surface. Many European sanitary ware manufacturers use brass alloy MS65 or MS63 (stamped) with a high zinc content that is resistant to zinc leaching. A good product should have sufficient weight.

But inexpensive cranes, mostly made in China, are made from low-quality alloys (aluminum plus silicon, etc.), so their weight is very light.

Where is brass used, metal composition, products manufactured

Brass is a metal that dates back to ancient times. In Ancient Rome it was used for various purposes, since its properties are not inferior to gold and silver. This alloy is still used in the manufacture of jewelry, pipes and plumbing materials. It has very specific properties, a wide range of applications and looks similar to copper.

Properties

The main properties include:

1. Easily processed using pressure.
2. Resistance to corrosion and weather conditions at the highest level.
3. Resistant to organic acids and carbon dioxide solutions.
4. Resistance to low and high temperatures.
5. High level of impact resistance, wear resistance, hardness.
6. Low level of deformation (both wrought and cast).
7. Contacts with other metals to improve production qualities.
8. Does not change the original characteristics over time.
9. Electrical resistivity – (0.07-0.08)·10−6 Ohm·m.
10. It turns black when oxygen comes into contact with the metal (to avoid this, it is coated with varnish).
11. Density 8300-8700 kg/m³.

Alloy composition

In the production of the alloy, secondary raw materials and waste are used. Various furnaces supporting high temperatures (900-950 degrees Celsius) are used for melting. zinc and copper are important constituents of the metal. Their ratio varies between 55-95% (copper) and 5-45% (zinc).

The brand is designated by the letter L, and the digital code next to it symbolizes the percentage composition of copper. The main color of brass is yellow. Other elements included in the composition can color it greenish, reddish or golden.

Thanks to this content, brass perfectly withstands any weather conditions, it is very stable and durable (it is even called an eternal metal). Additional (alloying) metals:

1. Aluminum (allows copper to be coated with a protective film and also reduces volatility levels).
2. Lead (improves the mechanical properties of brass).
3. Silicon (increases the level of hardness, reliability and strength, has an anti-friction effect).
4. Nickel (allows the metal to resist rust and rot).
5. Manganese (improves the anti-corrosion properties of brass, increases wear resistance).
6. Tin (used for the manufacture of brass alloys for sea and river navigation, as it increases the level of strength and resistance to water several times).

Areas of use

The scope of brass is extensive. These are various branches of human life. What is made of brass can be seen in the following examples:

1. For plumbing purposes (faucets, taps, nuts, couplings, pipes, washers).
2. On sea and river vessels (for instruments, equipment, pipes, profiles, hulls).
3. For automation (watch components, mechanisms and fasteners).
4. For the manufacture of shaped products.
5. For the manufacture of parts and elements for heat-conducting and chemical purposes (siphons, coils, capillary tubes).
6. For the production of jewelry and accessories (chains, bracelets, wire, beads).
7. For the production of furniture fasteners and accessories;
8. For the manufacture of dishes and decorative items;
9. For the manufacture of sconces, chandeliers, elements for use in electrics.

Non-ferrous rolled products

Non-ferrous rolling is the production of an alloy from zinc and copper in the required ratio. The release of this metal to the market is carried out by metallurgical plants that have permission for such activities. All manufactured goods (solid sheets, mesh, wire in coils) must comply with the norms, rules and technical recommendations established by the regulations of the Russian Federation.

Metal processing

When processing this metal, special methods are used to achieve special ductility and softness, and the formation of a crystal lattice. This requires certain proportions of zinc (32.5%) and copper.

This composition allows for easier and more precise further processing by drawing or rolling. Brass is used both cold and hot. Increased strength, hardness, ductility and durability are characterized by classes and grades LM70, L80, L68, LT90.

Elasticity and rigidity for mechanical processing are achieved precisely by the percentage ratio of zinc to copper.

Watch a video on how to identify and where to look for brass.

Pipes

Brass pipes are considered one of the best. They are wear-resistant, durable, reliable and not subject to corrosion. The brands L63 and L68 are produced. A special GOST has been established by law - rules for the production of this material. Models are divided into groups depending on specific characteristics. This:

1. Types.

• general use with high strength;
• with thin walls (considered light weight);
• waveguide;
• used for heat exchange equipment;
• used in mechanical engineering;
• capillary;
• used for radiators;
• intended for plumbing work;
• manometric.

2. Technical conditions.

• for general purpose;
• with thin walls.

3. By type of manufacture.

•  drawing (D – cold rolling method);
• pressing (D – hot deformation method).

4. Precision production.

5. According to the condition of the metal.

• soft – M;
• very soft – L;
• ¼ part solid – H;
• ½ part solid – P;
• ½ part solid with an increased level of plasticity - I;
• hard as a result of annealing at low temperatures - T.

6. By cross section.

• round;
• square;
• rectangular;
• hexagonal.

7. Special conditions.

• A – with antimagnetic properties;
• T – with the presence of curvature;
• K – with high precision curvature;
• L – with a high level of plasticity;
• G – pressed;
• C – welded blank;
• R – any workpiece.

Couplings and mixers

Plumbing materials made from brass are more durable, wear-resistant and of high quality, not subject to corrosion. Mixers, couplings, nuts are parts that are in demand on the market and have high properties. They are considered better and more reliable than stainless steel.

Their cost is higher, since the service life is really long. GROHE, for example, is one of the well-known companies that produces sanitary elements for sale. The company provides a 5-year or 10-year warranty.

This only means that the metal will withstand the warranty period.

Brass in jewelry

In jewelry, this metal has received one of the main places. It has long been considered counterfeit or false gold. It was used to make coins, jewelry, wire and cutlery. Then they began to make church utensils, medals and orders from it.

Previously, such products brought huge profits due to the lack of education and awareness of people. Today, many jewelry factories use brass to produce chains, earrings, rings, bracelets, wire for jewelry, and various accessories. The price of the products is low and far from gold.

This alloy is also in demand among needlewomen. Brass is number 1 as a handmade metal.

Brass occupies an important and honorable place among metals. The alloy, which resembles gold in appearance, is strong and durable. It is thanks to his individual characteristics that he is in demand in modern society.

Where to sell brass, its types and what is accepted at the scrap metal collection point

Let's start with the properties of brass; this alloy consists of two metals: copper and zinc.
Other elements allowed in the alloy are: lead, tin (a little), iron, manganese and nickel. Prices for scrap metal in Moscow change frequently; for brass, the price is determined by the copper content in the alloy, and accordingly depends on the quotation of this metal; with us you can always use a metal analyzer for the most honest assessment of your scrap metal and sell brass at the highest possible price.

Formation of brass categories

At scrap metal delivery points, brass is divided into several categories:

Brass mix

By and large, this group includes any brass parts and their components. These can be pieces of brass during production, machine parts left behind by pieces of brass after construction work. Most of the weight in this category comes from plumbing fixtures: valves, faucets, faucets, shower stands, and more.

Brass radiators 

By and large, brass radiators consist of brass tubes and sections, which in turn mostly consist of copper plates. We accept these items at our scrap metal collection points.

Brass shavings

We accept brass shavings in dry form (chipped and vine-shaped), we check that they are not magnetic (there are no other impurities), shavings of other alloys are not allowed. After inspection, the brass is accepted, prices are formed and weighed. Payment is made on the spot.

In the assessment of scrap brass, there are also other categories of waste. The first category contains brass trim, tape, rods, pipes and tubes, and wire materials. The second category includes waste from artistic products: broken musical instruments, furniture and decorative fittings.

You can hand over any scrap brass in Moscow at our scrap metal collection points; the addresses of metal collection points can be found in our contacts section. Choose the scrap metal collection point closest to you in Moscow.

With us you can sell any scrap non-ferrous metals; below you can see the prices.

What is made from brass

Brass, which is well known and has been actively used for many years, is an alloy of copper and zinc. The inventor of this material with a number of unique characteristics is considered to be the Englishman James Emerson, who patented it in 1781.

Brass metal products have good corrosion resistance and high strength

Composition elements

The basis of brass is copper and zinc. In the most traditional composition of such an alloy, copper is contained in an amount of 70%, and zinc - 30%. There are brands of technical brass that contain 48–50 percent zinc. Typically, more than 50% of the zinc used for the production of brass alloys is obtained from waste of this metal.

Depending on the characteristics of the internal structure, alpha- and alpha-beta-type brasses are distinguished, which are also called single- and two-phase.

Their main differences are as follows.

• The chemical composition of brass alloys belonging to the alpha type contains 35% zinc.
• Alpha-beta brass (two-phase) consists of 47–50% zinc. They also contain lead, the amount of which does not exceed 6%.

Despite the fact that brass, also based on copper, is very similar in appearance to some brands of bronze, according to the professional classification it does not belong to bronze alloys.

Some types of brass contain tin, the main alloying element of bronze, but it is added in very small quantities to improve certain characteristics of the alloy.

In addition to tin, the chemical composition of certain brands of brass may contain elements such as lead, manganese, iron, nickel, etc., which can also improve its properties.

Products made from brass have a beautiful golden-yellow color and lend themselves well to polishing and other types of machining.

Depending on the grade of the alloy from which the product is made, the latter can be forged in a cold or heated state, but some types of this metal cannot be processed by plastic deformation methods.

Despite the fact that brass is characterized by high corrosion resistance, the surface of products made of this metal, when exposed to ambient air for a long time, becomes covered with an oxide film and darkens. To prevent the surface of brass products from changing color over time, they are often coated with a protective layer of colorless varnish.

Chemical composition and features of the internal structure

To have a good understanding of the characteristics of brass, it is important to understand what properties the chemical elements of which it is composed have. Such elements, as mentioned above, are copper and zinc.

Classification of brasses by chemical composition

Copper is one of the first metals that man began to use for the manufacture of products for various purposes. This element, which is included in the 11th group of the IV period of the periodic table, has atomic number 29 and is designated as Cu (short for Cuprum). Copper, which is a transition metal, is highly ductile and has a beautiful light golden color. When an oxide film forms, the metal acquires an equally beautiful yellowish-red hue.

Zinc, the second main element in the chemical composition of brass, is also a metal that, unlike copper, does not occur in nature in its pure form. Zinc, having atomic number 30, is included in the secondary subgroup of the 2nd group of the IV period of the periodic table.

This metal, which began to be produced in the 12th century in India, is highly brittle under normal conditions. Without the oxide film that appears on the metal when it interacts with open air, its surface has a light blue color.

This metal is designated by the symbol Zn (short for Zincum).

This is what the microstructure of a polished brass surface looks like under 400x magnification.

The structure of brass, depending on the content of the main components in its composition, can consist of one α-phase or simultaneously α+β-phases. The states that the internal structure of the alloy can assume are distinguished by the following features:

• α-phase is a solution of copper and zinc, characterized by high stability, in which the molecules of the base metal (copper) have a face-centered cubic lattice;
• The α+β phase is also a stable solution in which copper and zinc are contained in a ratio of 3:2 (in such a solution, copper molecules have a simple unit cell).

The microstructure of α + β-brass has less ductility and greater hardness than the structure of α-brass

Depending on the heating temperature, the following structural transformations occur in brass.

• When brass is heated to high temperatures, the atoms in its β-phase, which has a wide range of homogeneity, are characterized by a disordered arrangement. In this heating state, the β-phase of the brass alloy is highly ductile.
• When a brass alloy is slightly heated (454–468 ° ), a phase designated β' is formed in it. A feature of this structural phase, which is characterized by high hardness and, accordingly, brittleness, is that the copper and zinc atoms in it are arranged in an orderly manner.

Based on the foregoing, we can conclude that brass alloys, the internal structure of which is only the α-phase (single-phase), are distinguished by good ductility, and those in which the β-phase is also present (two-phase) are more durable, but not intended for processing by plastic deformation methods.

The ductility of brasses with a two-phase structure can be increased if they are heated above the temperature at which the β'-transformation occurs (700 ° ).

In this state, only one β-phase predominates in the structure of the alloy; accordingly, it is characterized by high plasticity. However, even single-phase brasses with good ductility can practically not be processed by plastic deformation methods.

This occurs in the temperature range of their heating to 300–700 ° , which is called the brittleness zone.

A variety of uses for brass in everyday life and construction

Artistic casting from bronze and brass is a popular trend in modern industry. Brass is one of the most common and industrially important copper alloys. It completely retains the unique properties of copper, but at the same time it is more affordable and in some cases has higher strength.

The scope of application of the alloy is very wide. The production of high-precision parts from brass, ball valves, badges, the production of plates and rods from brass - we will talk about all this today.

The alloy has been known for a very long time and found its first application in jewelry. Unlike bronze, brass can be forged at a much lower temperature, and in many cases even cold forging is possible.

Its color is extremely reminiscent of gold, and its resistance to corrosion, although less, is also impressive. Today, brass jewelry successfully competes with gold jewelry. And, considering that the alloy is not considered precious, that is, despite all its decorative properties, it costs much less, its popularity is completely justified.

In jewelry, two-component brass alloys are used, that is, containing only copper and zinc, and with a larger proportion of copper. This is yellow brass - 67% copper and 33% zinc, golden or tombac - 75% copper and 25% zinc, and green - 60% and 40%, respectively. Alloys are deformed at temperatures up to 300 C, and small objects made of thin wire are deformed without heating at all.

• Two-component the compositions are characterized by higher plasticity. However, when the temperature rises above 300 C, its plasticity decreases. This feature determines the scope of application.
  • This area is not limited to jewelry. Two-component brass is actively used in the production of nuts, bushings, cages, bearings and other fittings that do not heat up above 300 C during operation. For this purpose, it is no longer jewelry brass that is used, but foundry brass, intended for the manufacture of shaped parts by casting. It differs in its lower copper content – ​​50–60%. This composition reduces ductility but increases strength, which is necessary for machine parts.
  • Alloys with a very high copper content - 85–96% are used for the manufacture of radiators, capillary tubes, coils, bellows and other parts for chemical and thermal equipment. Reason: copper, and, accordingly, such an alloy excellently transfers and distributes heat and is very resistant to corrosion.
• Multicomponent brass includes, in addition to 2 main metals, other additives - iron, nickel, lead, manganese and so on. Each such ingredient affects the properties of the alloy and expands the scope of application.
  • Automatic brass with a copper content of 57–80%, zinc 24–42% and with the addition of lead is used for the manufacture of the entire mass of nuts, bolts, watch parts, and so on, where fine machining is required. Lead promotes the formation of loose chips when processing the workpiece, and this speeds up the process and reduces wear on the separating mechanism. Automatic brass is produced in the form of sheets, rods, strips, etc., and then the material is used to produce machine parts.
  • Marine brass is an alloy alloyed with tin. The latter gives the material high resistance to sea water. The brass composition is used for the manufacture of profile products, pipes, and instrument housings in shipbuilding. It is also used to make condenser pipes for heating equipment.
  • The alloy alloyed with iron also exhibits higher resistance to water. It is used in the manufacture of parts for sea and river vessels.

We will talk about the extrusion production of brass products and other areas below.

This video will tell you how brass is refined and degassed in an induction channel furnace:

In construction work, if we mean all finishing engineering work, brass is also used quite often. The most famous area is decorative accessories, since the material is very beautiful in appearance, durable enough for household use and can be easily forged. However, it also has other uses.

Best answers

Do you need a lot of material if you are making it for yourself? You made spinners and jigs yourself. Ask the guys from the factory, the tool makers definitely have it, they’ll share. You can look at the car spare parts market, where the guys on the shelves sell a lot of interesting things, for example, copper gaskets, etc., various tubes made of non-ferrous metal, and you can also find rolled 0.2-0.3.

first you can go to a metal collection point or to the iron market and ask the men there

ask old photographers, they probably still have glossers - devices for drying photos, they have excellent brass

Previously, in our city there was an art fund store that supplied artists with the necessary materials for their creativity. They also pressed sheet brass of different thicknesses, as well as copper and cupronickel. Now only old stock remains. Vasily suggested a business with glossers, but there is another option - brass and copper tubes. They are easier to get, and sawing along their lengths, annealing them to relieve stress and straightening them is not difficult.

Cut a brass sleeve of 12 or 16 gauge along the sleeve into plates.

Better yet, buy a lure in the store! It’s no longer possible to make a spinner

It’s easier to contact the san.
technicians. Ask them for hangers from old faucets and faucets. axle boxes Well, if you're lucky, they might give away the entire mixer. The gander (that’s what they call the tube that stands at the outlet of the mixer) is usually nickel-plated, cut it lengthwise and you’ll have brass into petals. From the tap. An axle box on which there is no thread (screw) makes an excellent body for a spinner. If you carefully cut the mixer itself, you will get good plates for vibrators. This is how I make spinners myself.
