Copper-nickel alloys comprise 2 to 30% nickel and have high oxidation resistance and stress corrosion cracking resistance. Their high oxidation resistance is seen in moist air and steam. These alloys are thermally stable and possess moderate strength even when the temperature is high. The corrosion resistance and strength of these alloys are improved by the addition of manganese, iron, niobium, and or chromium. Copper nickel alloys also have good fabricability and high inherent resistance to biofouling.

The soluble nature of nickel in copper provides the copper nickel alloys with single phase alpha structures. The alpha dendrites in the cast structures contain a large amount of nickel starting from the center up to the edge of the dendrite. A large quantity of nickel is also present in interdendritic regions. The dendrite structure is broken by mechanical treatments. The alloying elements do not get homogenized even by repeated thermal and mechanical treatments.
