Background

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.

Brass Classes

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. CZ114 is a duplex or alpha/beta alloy.

Alloy CZ114

Brass alloy CZ114 is a versatile high strength, hot workable, machinable engineering alloy.
