Brass: general information

Technical Characteristics

Brass is an alloy based on copper and zinc (which in an alloy can be from 4% to 50%). Brass has been mined since before our era. Until the end of XVIII century, it was obtained by melting copper and zinc ore, which was mixed with charcoal. Only in XIX century such method was replaced by a direct way of alloying of copper and zinc. Because of its strength, ductility, corrosion resistance, ease of processing under pressure, comparative cheapness and attractive aesthetic appearance, this metal has become the most common copper alloy. Brass is used to produce sheets, rods, strips, wire (of deformable grades), pipes and castings (of foundry grades). The color of the alloy varies from light yellow to reddish, depending on its copper and zinc content. Today, it is possible to buy brass alloy of any composition under order.

Brass Types

Simple brass is called an alloy of copper and zinc. If copper is 90% and zinc 10%, the alloy is called tompak, and if the zinc content is from 10 to 20% - semi-tompak. Such alloys, which have high ductility and corrosion resistance, are used in the production of condenser and radiator tubes, ribbon, sheets for steel cladding. Alloy, which contains about 30% of zinc, has the ability to deep drawing, it is called cartridge. This brass is widely used in the manufacture of products by pressing, drawing, and cold stamping.

Basic Additives

To improve the anti-corrosion, mechanical and anti-friction properties of brass, they add to double copper alloys with zinc - tin, aluminum, iron, silicon, nickel, manganese, lead and other elements (in total up to 10%). Multicomponent (or special) brass is called aluminum, silicon, aluminum-nickel, iron-manganese , etc. Brass, which contains about 0.5% aluminum and 15% zinc, has a high resistance to atmospheric corrosion and a golden beautiful color. This brass alloy is used as a gold substitute for artwork and insignia. Brass with up to 1.5% lead (also called marine brass) is highly corrosion resistant even in sea water, and up to 3% lead makes the chips brittle and produces a high surface finish when being cut. Leaded brass (also called clock brass) is used in the watchmaking and automotive industries.
