Resistance Wire - Omega Resistance Wire

Knight Precision Wire manufacture resistance wire materials and products under the brand Omega Resistance Wire.

We are a well-established and highly-qualified manufacturer of electrical resistance wire and nickel chromium alloy wire for applications demanding high quality, reliability and service.

Our products are produced to the highest international standards, and we export worldwide to some of the most distinguished companies.





Why use Resistance Wire?

Resistance Wire offers a number of advantages across a range of applications. The material’s high resistivity, particularly in short wire applications, makes it ideal for use in products requiring managed heat properties, and high-temperature and coiled heat applications including:

  • heat treatment
  • control resistors
  • thermocouples
  • electrical heating elements (toasters, heated seats, blow dryers, electric heaters)
  • glass sealing applications

What alloys does Knight Precision Wire use for Resistance Wire?

In many applications, the stability of the resistor is of primary importance, and thus the alloy's temperature coefficient of resistivity and corrosion resistance determine the material selection.

Depending on your needs and the application requirements, we are able to provide Resistance Wire using the following alloys:

  • Iron Chrome Aluminium: ICA135, 145
  • Nickel Chrome:  NiCr80/20, NiCr60/16, NiCr37/18
  • Copper Nickel: CuNi44, CuNi30, CuNi6
  • Nickel Iron: NiFe42, NiFe48, NiFe52, NiFeCo
  • Pure Nickel and Alloy: 200, 212
