Key features:

Fine-grained structure for improved strength and wear resistance. Suitable for higher-stressed, fast-running worm gears and helical gears.


Full alloy description:

A.W. Fraser Alloy CuSn12Ni is a nickel bearing tin bronze meeting the requirements of DIN 1705 - 1981 alloy GC - CuSn12Ni.

This alloy has improved strength and wear resistant characteristics and is corrosion resistant and sea water resistant to cavitation stresses.

CuSn12Ni is suitable for higher stressed fast running worm wheel rims and helical gear wheel rims. It also has uses in severely stressed housings for fittings and pumps, guide wheels, runners and bucket wheels for wheels for pumps and water turbines.

The composition of A.W. Fraser alloy CuSn12Ni is strictly controlled as are the casting conditions.

CuSn12Ni products are manufactured using the latest continuous casting technology.
