You don't know the nickel base alloy knowledge book


Nickel-based alloys composed of other elements are called nickel alloys. Nickel has good mechanical, physical and chemical properties, adding suitable elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve some physical properties. Nickel alloys can be used as materials for electronic tubes, precision alloys (magnetic alloys, precision resistance alloys, electric heat 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.

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

Nickel base alloy Definition

Nickel-based alloys are generally called alloys with Ni content exceeding 30wt%, and common products have Ni content exceeding 50wt%. Due to their high-temperature mechanical strength and corrosion resistance, they are collectively called alloys (Superalloy) 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, it is mostly used in corrosion-resistant environment, high-temperature corrosive environment, and equipment that requires high-temperature mechanical strength. Often used in aerospace, energy, petrochemical industry or electronics/optoelectronics and other fields.
