A nickel-based alloy in which other elements are added. Nickel has good mechanical, physical and chemical properties, adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve some physical properties. Nickel alloy can be used as valve material, precision alloy (magnetic alloy, precision resistance alloy, electric heating alloy, etc.), nickel base high temperature alloy, nickel base corrosion resistant alloy, shape memory alloy, etc. Nickel alloys are widely used in energy development, chemical industry, electronics, navigation, aerospace and other fields. Pure nickel has good electrical conductivity and corrosion resistance, its high melting point, within the working temperature range of the cathode, will evaporate; Have enough heat evaporation, and have good machining performance and formability; It has a good effect on the emission of the cathode, and has an appropriate resistivity, good radiation coefficient and large heat conduction coefficient. Therefore, it is mainly used for corrosion resistant components. Precision instrument structure and important parts of equipment, such as chemical corrosion resistance equipment, production of strong alkali filter (cloth), and welding pig iron electrode core wire, lamp bulb factory lamp pin lead, heating rod lead, etc.
