Brass is an alloy of copper and zinc. The simplest brass is a copper zinc binary alloy, which is called simple brass or ordinary brass. Brass with different mechanical properties can be obtained by changing the content of zinc in brass. The higher the content of zinc in brass, the higher its strength and lower its plasticity. The zinc content of brass used in industry does not exceed 45%. The higher the zinc content, the brittleness will occur and the alloy performance will deteriorate. In order to improve some properties of brass, the brass added with other alloy elements on the basis of single brass is called special brass. Common alloy elements include silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass can improve its yield strength and corrosion resistance, and slightly reduce its plasticity. Brass containing less than 4% aluminum has good processing, casting and other comprehensive properties. Adding 1% tin to brass can significantly improve its corrosion resistance to seawater and ocean atmosphere, so it is called "naval brass". Tin can also improve the machinability of brass. The main purpose of adding lead to brass is to improve the machinability and wear resistance. Lead has little effect on the strength of brass. Manganese brass has good mechanical properties, thermal stability and corrosion resistance; Adding aluminum to manganese brass can also improve its properties and obtain castings with smooth surface. Brass can be divided into casting and pressure processing products.
