CZ115 (CW722R)


CZ115 (CW722R)

CZ115 (CW722R) is a duplex high tensile brass with a restricted aluminium content to facilitate soldering and brazing. Sometimes referred to as a manganese bronze, CZ115 (CW722R) has additions of iron, tin and manganese that benefit the physical and mechanical attributes of the alloy. The grade was developed to allow high strength brass components to be joined.

The additions of tin and iron contribute to improved strength levels, with the tin content improving the corrosion resistance. CZ115 (CW722R) also offers good machinability, ease of hot forging and lends itself to finish plating.
