Copper nickels.
High Strength Copper Nickels. The principle high strength Cu-Ni alloys result from the fact that the addition of aluminium to a Cu-Ni binary alloy increases the strength through the formation of age-hardening precipitates. This effect has been known since the 1930’s, and a number of alloys have been produced based on the Cu-Ni-Al system.
Copper-nickel (also known as cupronickel) alloys are widely used for marine applications due to their excellent resistance to seawater corrosion, low macrofouling rates, and good fabricability. They have provided reliable service for decades while offering effective solutions to today’s technological challenges.
