Due to the different zinc content in brass, the mechanical properties are also different. The mechanical properties of brass vary with the zinc content. For α brass, both σb and δ increase continuously with the increase of zinc content. For (α+β) brass, the room temperature strength increases until the zinc content increases to about 45%. If the zinc content is further increased, the strength will decrease sharply due to the appearance of a more brittle r-phase (solid solution based on Cu5Zn8 compound) in the alloy structure. (α+β) The room temperature plasticity of brass always decreases with the increase of zinc content. Therefore, copper-zinc alloys with a zinc content of more than 45% have no practical value.
Ordinary brass has a wide range of uses, such as water tank belts, water supply and drainage pipes, medals, bellows, serpentine pipes, condenser pipes, bullet cases, and various punching products with complex shapes, small hardware, etc. With the increase of zinc content from H63 to H59, they can withstand hot processing well, and are mostly 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 (generally 1% to 2%, a few up to 3% to 4%, and very few up to 5% to 6%) is added to the copper-zinc alloy. %), tin, aluminum, manganese, iron, silicon, nickel, lead and other elements form ternary, quaternary, or even quinary alloys, which are complex brass, also known as special brass.
