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.
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.

Nichrome is used as resistance wire for heating elements in things like toasters and space heaters. These uses make chromium a strategic material. Consequently, during World War II, U.S. road engineers were instructed to avoid chromium in yellow road paint, as it "may become a critical material during the emergency". [73]

Magyar Tudomány (Hungarian pronunciation: [ˈmɒɟɒr ˈtudomaːɲ], Hungarian: Hungarian Science) is the official monthly science magazine of the Hungarian Academy of Sciences. It publishes short articles on various new scientific developments as well as on problems of scientific life. Most articles are written by members of the academy.
