Copper Alloys, BrassCW606N (CZ131) Bar

A brass for machining, fasteners and rivets.

Brasses are alloys of copper and zinc. They may also contain small amounts of other alloying elements to impart advantageous properties. Brasses have high corrosion resistance and high tensile strength. They are also suited to fabrication by hot forging. Free machining grades of brass set the standard for machining, by which other metals are compared.

CW606N/CZ131, designed to provide a compromise between machinability, ductility and strength, is a riveting and turning brass with a duplex phase structure containing a fine dispersion of lead particles to improve machinability.
