Complete knowledge of nickel base alloys you don't know


An alloy made of nickel and other elements is called nickel alloy. Nickel has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and some physical properties. Nickel alloys can be used as materials for electronic tubes, precision alloys (magnetic alloys, precision resistance alloys, electrothermal alloys, etc.), nickel base superalloys, nickel base corrosion resistant alloys and shape memory alloys. Nickel alloys are widely used in energy development, chemical industry, electronics, navigation, aviation and aerospace.

Nickel can form a variety of alloys with copper, iron, manganese, chromium, silicon and magnesium. Nickel copper alloy is a famous Monel alloy with high strength and good plasticity. It has stable chemical properties in the atmosphere below 750 degrees. It is widely used in electrical industry, vacuum tube, chemical industry, medical equipment and marine industry.

Definition of nickel base alloy

Nickel base alloys are generally called alloys with Ni content of more than 30wt%, and common products have Ni content of more than 50wt%. Due to their high-temperature mechanical strength and corrosion resistance, they are called superalloys together with iron-based and cobalt based alloys. They are generally used in high-temperature environments above 540 ℃, and different alloy designs are selected according to their application occasions. They are mostly used in corrosion-resistant environments, high-temperature corrosion environments Equipment with high temperature mechanical strength is required. It is often used in aerospace, energy, petrochemical industry or electronic / photoelectric fields.
