Web80-20 Nickel-Chromium Electrical Resistance Wire Chromel A is an alloy used at operating temperatures up to 2150 ° F (1200°C). Its 80% Ni/20% Cr chemical composition gives good oxidation resistance. Its low temperature coefficient of resistance ensures fast heat up times and stable operating temperatures over its entire range of use. WebJul 1, 2024 · Since the chromium ions do not contribute to the conduction process due to its stable valence state [27], the number of electrons hopping between Fe2+ and Fe3+ decreases, leading to an enhanced resistivity. However, abnormal decrease of electrical resistivity at x=0.2 and 0.3 is observed.
