An alloy consisting of other elements based on nickel. The Monel (Monel) alloy produced before and after 1905, which contains about 30% of copper, is an earlier branch nickel alloy. Nickel has good mechanical, physical and chemical properties, and adding suitable elements can improve its antioxidant, corrosion resistance, high temperature strength and improve some physical properties.
The nickel alloy can be used as a material for tube, precision alloy (magnetic alloy, precision resistance alloy, electrothermal alloy, etc.), nickel-based superalloy and nickel-based corrosion-resistant alloy and shape memory alloy. In the energy development, chemical industry, electronics, navigation, aerospace and other departments, the branch nickel alloy are widely used.
