CZ112 (CW712R) Brass AlloyCZ112 (CW712R) Brass Alloy

CZ112 is commonly referred to as a Naval brass and is used typically in a wide range of marine and subsea applications.

This brass alloy offers superior strength and corrosion resistance and offers good property retention at cryogenic temperatures. With excellent hot formability and very good corrosion resistance, the material is used extensively in the marine, oil & gas and petrochemical sector. The composition of the alloy, with 60% copper, 39% zinc and the important addition of 1% tin results in improved corrosion resistance and mechanical properties.

Key Features:

CZ112 offers improved corrosion resistance and better strength levels than alpha brasses. With excellent hot formability, CZ112 has a harder and stronger duplex structure.
