Nichrome

Nichrome is a non-magnetic alloy of nickel and chromium. Typically, the alloy is 80% nickel and 20% chromium. It is silvery-grey in colour, is corrosion resistant, and has a high melting point of about 1400 ?C. 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. Typically, nichrome is wound in wire coils to a certain electrical resistance, and current passed through to produce heat.

Nichrome is used in the explosives and fireworks industry as a reliable ignition system. The alloy tends to be expensive due to its high chromium content.

Alloy: An alloy is a combination, either in solution or compound, of two or more elements, which has a combination of at least two metals, and where the resultant material has metallic properties. An alloy with two components is called a binary alloy; one with three is a ternary alloy; one with four is a ...
