Copper+Nickel Alloy Pipe consisting of copper and nickel alloy; it is proper to use at high temperature due to its high degree of corrosion and seawater resistance. Application: It is mainly used in engine components, condensing engines, or sheaths. 25% nickel alloy is used to coins, 40% nickel alloy (constantan) is for thermocouple or electricity resistance wire. The monel metal that consists of a small amount of iron and silicon and 60-70% nickel alloy is used to turbin wings, valves or components of mine machines because it has a high degree of corrosion resistance and gets less damaged at high temperature.
