CW712R (CZ112) Bar

Brass alloy with the addition of tin, used in a wide range of marine and subsea applications.

CZ112/CW712R is commonly referred to as naval brass due its corrosion resistance in seawater and other mildly aggressive environments. The alloy contains 60% copper and 39% zinc, with a 1% tin addition for improved corrosion resistance and a harder and stronger duplex structure to improve the mechanical properties.

The increase in corrosion resistance enables the material to be used in both seawater and other mildly aggressive media, it also offers better strength levels than many of the basic alpha brasses combined with an excellent hot formability.
