Nickel-copper alloys are mostly used to make components, such as traveling wave tubes and magnetrons, which require high corrosion resistance, high temperature fatigue resistance and so on. Nickel-copper alloy is composed of 60% nickel, 33% copper and 6.5% iron. Nickel-copper alloy has good room temperature mechanical properties and high temperature strength, high corrosion resistance, good wear resistance, easy processing, non-magnetic, is a good structural material for Nickel-copper alloys ,Copper-Nickel alloys manufacturing traveling wave tubes and other electronic tubes. It can also be used as structural material of aeroengine.

Adding copper to nickel will have a series of effects on various properties of nickel, especially corrosion resistance, mechanical properties and physical properties. Generally, the addition of copper improves the corrosion resistance of nickel in reducing medium, but decreases the corrosion resistance of nickel in oxidizing medium and the oxidation resistance in air. The addition of copper increases the strength, hardness and plasticity of nickel, and decreases the plasticity slightly. The addition of copper increases the thermal conductivity of nickel.
