CuSn5Zn5Pb5

Bronze alloy

EN CW491K - UNS C83600

CuSn5Zn5Pb5 is a bronze alloy containing lead and zinc, designed for friction applications. It offers good machinability due to the presence of lead and effective anti-friction properties for bearings and bushings. This alloy is primarily used in cast and machined parts where wear resistance and ease of machining are important.
