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.
