RW 80 Nickel-Chrome Resistance Wire
An alloy wire used at operating temperatures up to 1200°C. Its
chemical composition gives good oxidation resistance especially
under conditions of frequent switching or wide temperature fluctuations.
Applications include heating elements in both domestic and industrial appliances and in control resistors.
