Key Features
The addition of nickel to copper improves strength and corrosion resistance but good ductility is retained. Copper-nickel alloys have excellent resistance to marine corrosion and biofouling.
Copper-nickel alloys are widely used for marine applications due to their excellent resistance to seawater corrosion, high inherent resistance to biofouling and good fabricability. They have provided reliable service for several decades whilst offering effective solutions to today's technological challenges.
Typical Uses
Cupro-nickel is used extensively in sea water application where its excellent corrosion resistance and ani fouling properties make it a popular alloy for offshore oil platforms, fish farms and general marine cladding where sea growths are a problem.

EN 12420 CW354H
A European copper alloy forging standard for 70/30 Cupro Nickel CuNi30Mn1Fe CW352H.The alloy has higher mechanical properties than 90/10 cupro nickel and can withstand greater water flow rates. The addition of manganese and iron aids corrosion resistance It has good resistance to bio-fouling and does not suffer from stress corrosion and is ideal in aggressive marine environments. The alloy can also be produced to several other world specifications EN1652/1653/12163/12165 CW354H and Def Stan 02-780 Part 2 and Def Stan 02-879 Part 1 and Part 2, DIN 17670/17672/17675, BS 2870/2872/2874/2875 CN107, ASTM B 122/171/151 C71500, JIS H 3320/3100 C7150, AS 2738-2, NF A 51-115 and GOST 00492 MNZMc30-1-1.
