Description

CZ131 (CuZn37Pb2) is a riveting and turning brass consisting of a duplex phase structure with a fine dispersion of lead particles. The alloy offers good strength and ductility with a high general corrosion resistance. The copper content of this alloy is still sufficiently high to provide reasonable cold heading and forming properties, while the lead content provides good machinability.
