Alloy 400 is a copper-nickel alloy with excellent corrosion resistance, good corrosion resistance in various media, good welding performance, high strength and moderate strength. This alloy has been widely used in many occasions. It has excellent resistance to pitting corrosion and stress corrosion in salt water or sea water. Especially resistant to hydrofluoric acid and hydrochloric acid. It is widely used in chemical, petroleum and marine industries. It has good corrosion resistance and oxidation resistance below 980℃, high strength below 800℃, good relaxation resistance below 540℃, and good formability and welding performance. The alloy is mainly used to manufacture aero-engines working below 800℃ and require high strength corrosion-resistant ring parts, structural parts, bolts and other parts, and working below 540℃ with medium or low stress and requiring relaxation resistance. Springs and coil springs. It can also be used to make parts such as gas turbine blades
