An alloy composed of nickel and other elements. Monel alloy containing about 30% copper produced around 1905 is an earlier nickel alloy. nickel Alloy has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and certain physical properties. Nickel alloys can be 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 sectors.
