Nichrome is a name for a nickel-chromium resistance wire, a non-magnetic alloy of nickel and chromium.
A common alloy is 60% nickel, 15% chromium, and 25% iron by weight, 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). For heating, resistance wire must be stable in air when hot which is where nichrome excels. Typically, Nichrome is wound in wire coils to a certain electrical resistance, and current passed through to produce heat.
Due to its relatively high resistivity and resistance to oxidation at high temperatures, it is widely used in heating elements, such as in hair dryers, electric ovens and toasters.
Nichrome is used in the explosives and fireworks industry as a bridgewire in reliable electric ignition system, such as electric matches and model rocket igniters. Other areas of usage include motorcycle silencers, and in certain microbiological lab apparatus.
Nichrome wire is commonly used in ceramics as an internal support structure to help some elements of clay sculptures hold their shape while they are still soft.
Nichrome wire is used because of its ability to withstand the high temperatures that occur when a clay work is fired in a kiln. Nichrome wire forms a protective layer of chromium oxide. [1]
