Nickel-based alloys are a type of alloy that exhibits high strength and certain anti-oxidation and corrosion resistance at high temperatures ranging from 650 to 1000°C. Based on their primary properties, they are further categorized into nickel-based heat-resistant alloys, nickel-based corrosion-resistant alloys, nickel-based wear-resistant alloys, nickel-based precision alloys, and nickel-based shape-memory alloys. High-temperature alloys are classified according to the base material, including iron-based, nickel-based, and cobalt-based high-temperature alloys. Nickel-based high-temperature alloys are commonly referred to as nickel-based alloys.
