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.
