Brass Sheet CZ121

Brass Sheet CZ121 is a flat sheet of CZ121 Brass Alloy. CZ121 Brass Alloy is a free-machining brass consisting of a duplex phase structure with a 3% lead content. Particles of lead are finely dispersed throughout the microstructure, acting as both a lubricant and a chip breaker to give the alloy its free-machining characteristics.
