Brass is an alloy composed of copper and zinc. Brass composed of copper and zinc is called ordinary brass. If it is a mixture of two or more elements, it is called special brass.

The mechanical properties of brass are different due to the different zinc content, and the mechanical properties of brass vary with the amount of zinc.

With the increase of zinc content from H63 to H59, they can withstand the hot processing well, and are used in various parts of machinery and electrical appliances, stamping parts and musical instruments.

In order to improve the corrosion resistance, strength, hardness and machinability of brass, a small amount is added to the copper-zinc alloy (generally 1% to 2%, a few 3% to 4%, and very few 5% to 6). %) Tin, aluminum, manganese, iron, silicon, nickel, lead and other elements, constitute a ternary, quaternary, or even five-element alloy, which is a complex brass, also known as special brass.
