{{Short description|Family of alloys of mainly nickel and chromium}}
'''Nichrome''' (also known as '''NiCr''', '''nickel-chromium''' or '''chromium-nickel''') is a family of [[alloy]]s of [[nickel]] and [[chromium]] (and occasionally [[iron]]<ref name="sciencing">{{cite web |last1=Flournoy |first1=Blake |title=What Is Nichrome Wire Used for? |url=https://sciencing.com/nichrome-wire-used-for-5871336.html |website=sciencing.com |access-date=28 October 2019}}</ref>) commonly used as [[resistance wire]], [[Heating element|heating elements]] in devices like [[Toaster|toasters]], [[Electric water boiler|electrical kettles]] and [[Space heater|space heaters]], in some [[dental restoration]]s (fillings) and in a few other applications.

Patented in 1906 by [[Albert L. Marsh|Albert Marsh]] (US patent 811,859<ref>[https://patents.google.com/patent/US811859A/en?oq=811859"US Patent 811,858"]</ref>), nichrome is the oldest documented form of resistance heating alloy.

The A Grade nichrome alloy is 80% nickel and 20% chromium by mass, but there are many other combinations of metals for various applications.
