The so-called nickel-based alloy refers to an alloy based on nickel and added with other metals, such as tungsten, cobalt, titanium, iron, and other metals. There are many types of nickel-based alloys according to different classification methods. According to the matrix, nickel-based alloys can be divided into iron-based superalloys, nickel-based superalloys, and cobalt-based superalloys. The nickel-based superalloy can also be referred to simply as a nickel-based alloy. In addition, nickel-based alloys can also be divided 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. The types of nickel-based alloys will be briefly introduced here. Let’s talk about the grades of nickel-based alloys.

 

Nickel-based alloy grades are not mentioned, for now, let’s talk about the materials of nickel-based alloys:

 

1. Incoloy alloy, such as Incoloy800, the main composition is; 32Ni-21Cr-Ti, Al; belongs to heat-resistant alloy;

 

2. Inconel alloy, such as Inconel600, the main component is; 73Ni-15Cr-Ti, Al; belongs to heat-resistant alloy;

 

3, Hastelloy alloy, namely Hastelloy, such as Hastelloy C-276, the main component is; 56Ni-16Cr-16Mo-4W; belongs to corrosion-resistant alloy;

 

4. Monel alloy, that is, Monel alloy, such as Monel 400, the main component is; 65Ni-34Cu; belongs to corrosion-resistant alloy.
