Datasheet: 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
Heating elements in both domestic and industrial appliances and in control resistors.
