PRODUCT DESCRIPTION

Nickel-based alloys are alloys that have a combination of high strength and certain resistance to oxidation and corrosion at high temperatures of 650 to 1000 °C. According to the main performance, it is subdivided into nickel-based heat-resistant alloy, nickel-based corrosion-resistant alloy, nickel-based wear-resistant alloy, nickel-based precision alloy and nickel-based shape memory alloy. Superalloys are classified into iron-based superalloys, nickel-based superalloys and cobalt-based superalloys according to the matrix. Among them, nickel-based superalloys are referred to as nickel-based alloys.
