wire-stockist-productsAll of the Omega Resistance Wire products are Nickel based, with the exception of the ICA Alloys – which are alloys of Iron Chromium and Aluminium, but which exhibit very similar electrical resistance properties as the nickel chrome alloys.

The alloying of various elements with nickel produces electrical and physical properties that are diverse. Some have been developed for their electrical resistance properties, and some for their strength and corrosion resistance at high temperatures.

Nickel Chrome Alloys

products-stainless-steelNickel Chrome alloys, or Nichrome alloys have excellent electrical resistance properties, operating at temperatures up to 1200 °C. This property coupled with high resistance to oxidation and chemical corrosion makes these alloys ideal for use as resistance wires in furnaces and heat treatment applications.

Copper Nickel Alloys

Copper Nickel AlloyCopper Nickel alloys or Cupro Nickel alloys operate at temperatures up to 400 °C, have a low temperature coefficient of resistance and medium resistivity, plus high resistance to oxidation and chemical corrosion. Typical applications are electrical resistors and thermocouples.

ICA Alloys

products-nickel-alloysICA Alloys or Iron Chrome Aluminium alloys are ferromagnetic alloys that can be used as resistance wire, particularly in electrical heating elements. These alloys can operate at high temperatures up to 1250°C, but suffer from higher corrosion than nickel chrome alloys.

Nickel Iron Alloys

products-copper-alloysNickel Iron Alloys or Glass Sealing Alloys have a low and constant thermal expansion. As the coefficient of thermal expansion approximately matches that of glass, the alloy is used extensively as a glass seal in the manufacture of lamps and electronic equipment.

Nickel Alloys

products-special-wire-materialsNickel Alloys – the most common of which are Nickel (Alloy 200), Monel (Alloy 400) and Inconel (Alloy 600) – exhibit very high strength and corrosion resistance at elevated temperatures, plus excellent electrical resistance.
