Special Copper Alloy Tube
Copper nickel alloy : an alloy pipe consisting of copper(Cu) and nickel(Ni) which is highly wear/seawater resistant and suitable for high temperature
Use
Used in engine component, condensing engine, or sheath of bullet; 25% Ni alloy is used for coins, 40% Ni alloy(constantan) for thermocouple or electric resistance wire, and 60-70% Ni alloy with a small amount of Fe and Si (monel metal) is used in turbine wing, valve, or mining machines’ components because it is greatly wear-resistant and reduces a little in strength even if it is heated at a high temperature.
