What are the applications?
Resistance wires are manufactured from nickel alloys which have specialist properties such as electrical resistance, oxidation resistance, strength and corrosion resistance – all at elevated temperatures.
Resistance wire is thus used primarily in resistance heating elements, hot wire cutting, heat sealing, resistors and springs and fasteners for high technology industries. It is also used extensively as a glass sealing element.
