80/20 Ni Cr Resistance Wire (For Springs)

Nickel Base Wire for wire springs, flat springs and wire products

An alloy wire used at operating temperatures up to 1200°C (2200°F). Its chemical composition gives good oxidation resistance especially under conditions of frequent switching or wide temperature fluctuations.
80/20 Ni Cr Resistance Wire is also known as Nichrome / Nicrove V, Brightray C, Cronix 80, Nicrothal 80, Chromalloy, Chromel, and Gilphy 80.

Key Features

  • Low expansion alloy. Maintains near constant dimensions over the range of normal atmospheric temperatures.
  • Low coefficient of expansion from cryogenic temperatures to about +500°C (+930°F). Retains strength and toughness at cryogenic

Typical Applications

Heating elements in both domestic and industrial appliances and in control resistors

Approx. Operating Temperature

For use as a Heating Element 1200 °C/2200 °F (Maximum)
