Description

A 90/10 cupro nickel CuNi10Fe1 with the additions of iron and manganese giving excellent corrosion resistance in fresh and sea water and anti-biofouling properties. Cupro nickel failures due to stress-corrosion cracking are unknown in seawater polluted with ammonia. The alloys are also immune to chloride and sulphide stress corrosion cracking. required for cold.
