Nickel Chrome Wire Nicr80/20 for Arc Spray Wire
1 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.
