Brass is an alloy of copper and zinc. The simplest brass is a copper-zinc binary alloy called simple brass or common brass. Brass with different mechanical properties can be obtained by changing the content of zinc in brass. The higher the zinc content in brass, the higher its strength and slightly lower plasticity. The zinc content of brass used in the industry does not exceed 45%. No matter how high the zinc content is, it will cause brittleness and deteriorate the performance of the alloy. In order to improve certain properties of brass, brass added with other alloying elements on the basis of unary brass is called special brass. Commonly used alloying elements are silicon, aluminum, tin, lead, manganese, iron and nickel. Adding aluminum to brass can improve the yield strength and corrosion resistance of brass, and slightly reduce the plasticity. Brass containing less than 4% aluminum has good comprehensive properties such as processing and casting. Adding 1% tin to brass can significantly improve the brass' ability to resist seawater and marine atmospheric corrosion, so it is called "Navy Brass". Tin also improves the machinability of brass. The main purpose of adding lead to brass is to improve machinability and wear resistance, and 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 performance and obtain castings with smooth surfaces. Brass can be divided into casting and pressure processing two types of products.
