Nickel alloys are alloys composed of nickel as a base and other elements. Nickel possesses excellent mechanical, physical, and chemical properties. 

The addition of appropriate elements can enhance its oxidation resistance, corrosion resistance, high-temperature strength, and improve certain 

physical properties. Nickel alloys are used as materials for electronic tubes, precision alloys (magnetic alloys, precision resistance alloys, electric heating 

alloys, etc.), nickel-based high-temperature alloys, nickel-based corrosion-resistant alloys, and shape memory alloys. Nickel alloys are widely used in energy 

development, chemical industry, electronics, navigation, aviation, and aerospace.
