Copper and Copper Alloys - Brass - CW606N Brass Bar

CW606N Brass Bar

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.
Brasses are divided into two classes. The alpha alloys, with less than 37% zinc, and the alpha/beta alloys with 37-45% zinc. Alpha alloys are ductile and can be cold worked. Alpha/beta or duplex alloys have limited cold ductility and are harder and stronger. CZ131 / CW606N is an alpha/beta alloy.
The composition of brass alloy CZ131 / CW606N has been designed to provide a compromise between machinability, ductility and strength. Thus, it can be used in applications when machinability and riveting are required.

Applications
CZ131 / CW606N is typically used in:
Fasteners
Rivets
Domestic appliances
Automotive engineering
Hose fittings
Intricate parts such as clock components
