DIN CuZn39Pb3 Lead Brass Seamless Tubes For Mechanical Engineering Industry
1. Description
DIN CuZn39Pb3 lead brass Lead brass is one of the most important and widely used complex brass.It has good machinability, wear resistance and strength. This brand of lead brass pipe is mainly used for various connectors in mechanical engineering, toilet or bathroom water fittings, as well as valves and valve stems. The low cost of lead brass is an important prerequisite for its wide application. Because it contains a variety of alloy elements and the content requirement is relatively loose, it lays a foundation for the comprehensive utilization of brass alloy raw materials.
