Nickel alloy

An alloy based on nickel and adding other elements. The Monel alloy containing about 30% copper, produced around 1905, is an earlier nickel alloy. Nickel has good mechanical, physical and chemical properties. Adding appropriate elements can improve its oxidation resistance, corrosion resistance, high temperature strength and improve certain physical properties. Nickel alloys can be used as materials for electron tubes, precision alloys (magnetic alloys, precision resistance alloys, electrothermal alloys, etc.), nickel-based high-temperature alloys, nickel-based corrosion-resistant alloys, and shape memory alloys. Nickel alloys are widely used in sectors such as energy development, chemicals, electronics, navigation, aviation and aerospace.

The difference between nickel alloy and stainless steel

The difference is easy to understand. The key lies in the word "base", which means "base". Nickel-based alloys are commonly understood as nickel. Based alloys, that is, nickel accounts for the highest percentage, usually more than 50%, such as Monel alloy, Hastelloy B, C series, etc., while stainless steel is essentially a kind of "steel", so iron accounts for the The highest percentage. For example, 304L, although it contains 9% nickel, the iron content reaches more than 70%, so it is a kind of stainless steel.
