Nichrome is a non-magnetic alloy of nickel, chromium, and often iron,
usually used as a resistance wire. Patented in 1905, it is the
oldest documented form of resistance heating alloy. A common alloy
is 80% nickel and 20% chromium, by mass, but there are many others
to accommodate various applications. It is silvery-grey in colour,
is corrosion-resistant, and has a high melting point of about 1400
°C (2552 °F). Due to its relatively high electrical resistivity and
resistance to oxidation at high temperatures, it is widely used in
electric heating elements, such as in hair dryers, electric ovens,
soldering iron, toasters, and even electronic cigarettes.
Typically, Nichrome is wound in coils to a certain electrical
resistance, and current is passed through to produce heat.
