Resistance wire is manufactured in a large range of alloys, with finished diameters from 3.25mm down to 0.06mm. When used as a heating element, resistance wire is usually wounded into coils. Many elements and alloys have been used as resistance wire for special purposes.

A Nichrome alloy containing long life additions that make it eminently suitable for applications subject to frequent electrical switching and wide temperature fluctuations. It may be used at operating temperatures up to 1200 °C and has good resistance to oxidation and chemical corrosion. A low temperature coefficient of resistance coupled with a high resistivity makes it suitable for control resistors.

Application

These elements are commonly found in precision heating applications such as Medical Diagnostics, Satellite, and Aerospace
Electrical appliance industry Ironing machines, water heaters, plastic moulding dies, soldering irons, metal sheathed tubular elements, cartridge elements.
