Which metal is the main element in the alloy nichrome?

Nickel is the main element in the alloy nichrome.

Nichrome is a family of nickel-chromium alloys, usually containing mostly nickel and a substantial amount of chromium. Some varieties also include iron or other elements. The alloy is valued for its high electrical resistance and ability to withstand high temperatures.

Nichrome is commonly used as resistance wire in heating elements. Toasters, hair dryers, electric ovens, kilns, and laboratory equipment can use nichrome wire to convert electrical energy into heat. The chromium helps form a protective oxide layer that improves resistance to oxidation at elevated temperatures.

The name nichrome combines the words nickel and chromium, which can make the composition seem evenly divided. In practice, formulations vary, and the nickel content is commonly the largest component. Nichrome should also be distinguished from stainless steel: both may contain chromium, but stainless steel is primarily iron-based, while nichrome is primarily nickel-based.
