Resistance wire resists the flow of electricity and converts the electrical energy into heat. The primary function of the wire is thus as a heating element, and we produce it in various forms which include round resistance wire, resistance tape, resistance ribbon and resistance strand.
It is critical that the resistance wires can maintain performance at very high temperatures and that they are resistant to corrosion. The wires that can withstand the highest temperatures are nickel alloys – nickel chrome, nickel chromium 80/20 and nichrome 60/16. Resistance wires for less demanding temperatures are copper nickel and cupro-nickel, nickel iron and iron chrome aluminium (ICA).
Our 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 primarily used in resistance heating elements, hot wire cutting, heat sealing, resistors and springs and fastenings for high technology industries. It is also used extensively as a glass sealing element.
A particular speciality is the production of resistance strand to meet customers’ specific requirements of resistance or size. Strands of 7, 19, 37 and 49 construction are produced as standard in a wide range of alloys. For applications that require annealed strands, the finished strand can be annealed using the strand annealing lines. Many strands are available from stock, and other strand configurations are available to order.
