Copper Alloys, BrassCW508L (CZ108) Sheet & Tube

An alpha brass with good hot and cold working capabilities.

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 hot forging. Free machining brass sets the standard for machining, by which other metals are compared.

CZ108/CW508L is a high purity cold forming brass. It is used when severe bending properties are required. It is one of the most popular sheet and plate grades due to its hot and cold working capabilities.
