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.Chemical Composition and Main Properties of NichromeProperties GradeNiCr 80/20NiCr 70/30NiCr 60/15NiCr 35/20NiCr 30/20Main Chemical CompositionNiBalanceBalance55.0-61.034.0-37.030.0-34.0Cr20.0-23.028.0-31.015.0-18.018.0-21.018.0-21.0Fe≤ 1.0≤ 1.0BalanceBalanceBalanceMax Continuous Service Temperature(oC)12001250115011001100Resisivity 20oC (Ω mm2/m)1.091.181.121.041.04Density (g/cm3)8.48.18.27.97.9Thermal Conductivity(KJ/m@ h@ oC)60.345.245.243.843.8Coefficient of Thermal Expansion(α × 10-6/oC)1817171919Melting Point( Ω )14001380139013901390Elongation(%)> 20> 20> 20> 20> 20Micrographic StructureausteniteausteniteausteniteausteniteausteniteMagnetic PropertynonmagneticnonmagneticnonmagneticWeak magneticWeak magnetic
