Nichrome (also known as NiCr, nickel-chromium or chromium-nickel) is a family of alloys of nickel and chromium (and occasionally iron [1]) commonly used as resistance wire, heating elements in devices like toasters, electrical kettles and space heaters, in some dental restorations (fillings) and in a few other applications.

Nichrome, a non-magnetic 80/20 alloy of nickel and chromium, is the most common resistance wire for heating purposes because it has a high resistivity and resistance to oxidation at high temperatures, up to 1,400 °C (2,550 °F). When used as a heating element, resistance wire is usually wound into coils.
It is also commonly called Nichrome 80-20, and is used for electric heating elements. Chromel C ...
Albert Marsh (August 16, 1877 – September 17, 1944) was an American metallurgist.In 1905 he co-invented the first metallic alloy from which a high-resistance wire could be made that could be used as a durable and safe heating element.
Most modern electric heating devices use nichrome wire as the active element; the heating element, depicted on the right, uses nichrome wire supported by ceramic insulators. Alternatively, a heat pump can achieve around 150% – 600% efficiency for heating, or COP 1.5 - 6.0 Coefficient of performance , because it uses electric power only for ...
Ni-Cr(Fe) resistance heating alloys, also known as nichrome or Chromel, are described by both ASTM and DIN standards. [2] [4] These standards specify the relative percentages of nickel and chromium that should be present in an alloy. In ASTM three alloys that are specified contain, amongst other trace elements: 80% Ni, 20% Cr; 60% Ni, 16% Cr ...
A toaster is a small electric appliance that uses radiant heat to brown sliced bread into toast, the color caused from the Maillard reaction.It typically consists of one or more slots into which bread is inserted, and heating elements, often made of nichrome wire, to generate heat and toast the bread to the desired level of crispiness.
