CZ112 / CW712R Naval Brass Extruded and Rolled is commonly known as Naval Brass due to its improved corrosion resistance in marine environments. The general composition is 60% copper, 39% zinc with an important 1% tin addition that gives an improved corrosion resistance together with 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.
