The mechanical properties and wear resistance of brass strips are excellent, and they can be used to manufacture precision instruments, parts for ships, gun barrel casings, etc. Brass sounds pleasant when struck, so instruments such as gongs, cymbals, bells, and horns are made of brass. According to the chemical composition, brass is divided into ordinary brass and special brass.
(1) Ordinary brass is a copper-zinc binary alloy. Due to its good plasticity, it is suitable for manufacturing sheets, rods, wires, tubes, and deep-drawn parts, such as condenser tubes, heat dissipation tubes, and mechanical and electrical parts. Brass with an average copper content of 62% and 59% can also be cast and is called casting brass.
(2) Special brass is formed by adding elements such as aluminum, silicon, manganese, lead, and tin to the copper-zinc alloy to obtain higher strength, corrosion resistance, and good casting properties. Such as lead brass, tin brass, aluminum brass, silicon brass, and manganese brass.
