Ni80cr20 Nicr Alloy Bright Surface Good Oxidation Resistance ROHS Certification
Ni80Cr20 bright Resistance strip Resistance Heating Flat for home automation
Introduction
The Nichrome chemical composition is nickel, chromium and ferrum, it used at operating temperatures up to 1200 degrees. Its chemical composition gives good oxidation resistance, especially under conditions of frequent switching or wide temperature fluctuations. They are used for electric resistances of appliances or for application of industrial furnaces.
