Brass is an alloy of copper and zinc. The most simple brass is copper-zinc binary alloy, called simple brass or popular brass. Tampering with the zinc content of brass can result in brass with different mechanical properties. The higher the content of zinc in brass, the higher the strength and the lower the plasticity. The amount of zinc in the brass adopted in the property does not exceed 45%. If the zinc content is high, brittleness will occur and the properties of the alloy will deteriorate. In order to improve the properties of brass, the brass with the remaining alloying elements on the base of the one-piece brass is called special brass. Commonly used alloying elements are silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass improves the yield strength and corrosion resistance of brass, with a slightly lower plasticity. Brass containing less than 4% aluminum has superior properties such as processing and forging. Adding 1% tin to brass can significantly improve the resistance of brass to salt water and terrestrial atmospheric corrosion, hence the name "Naval Brass". Tin can also improve the cutting properties of brass. The important goal of brass lead is to improve machinability and improve wear resistance. Lead has little effect on the strength of brass. Manganese brass has superior mechanical properties, thermal stability and corrosion resistance; adding aluminum to manganese brass can also improve its properties to obtain a bright surface casting. Brass can be divided into two types of products: forging and press working. The chemical composition of rare processing brass.
