ASTM C38000 Lead Brass Seamless Tubes For Mechanical Engineering Industry
1. Description
ASTM C38000 lead brass is one of the most widely used composite brass. It has excellent cutting performance, wear resistance and high strength. It is mainly used in various connectors in mechanical engineering, water fittings in washroom or toilets and bathrooms, as well as valves and valve stems. 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 lays a foundation for the comprehensive utilization of copper alloy raw materials.
