Lead brass is extremely important and is the most widely used complex brass. Lead brass is a complex brass with lead as the main added element. It is composed of four non-ferrous metals, Cu, Pb, Al and Zn, combined in a certain ratio. . Lead is rarely solid-soluble in copper-zinc alloys. It exists as an independent phase in the alloy and is distributed as free particles at the grain boundaries and within the grains. It not only has a lubricating effect, but also can break the chips into a shape, which can improve the machinability of brass. and wear resistance. The machinability of lead brass is proportional to the lead content, but when the lead content exceeds 3%, the machinability of copper is no longer significantly improved, and the hardness, strength and elongation of brass are reduced. Therefore, the main properties of lead brass can be summarized as wear resistance, corrosion resistance and good toughness.
It is mainly used to retain various connectors, valves, and valve stem bearings in mechanical engineering. Among them, hot forged valve blanks, lock making industry, and watch industry are the three important markets. The low cost of lead brass is an important prerequisite for its wide application. Its alloy composition can contain a variety of alloy elements, and the content requirements are relatively loose, which also lays the foundation for the comprehensive utilization of copper alloy raw materials.
