Datasheet: 80/20 Ni Cr Resistance Wire
80/20 Ni Cr Resistance Wire
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.
Available in all profile options
Typical Applications
Heating elements in both domestic and industrial appliances and in control resistors.
