Product Description
Product Description:
Resistance wire(heating wire) used at operating temperatures up to 1200. 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.
Ni-Cr materials are widely used in industrial electric furnaces, household appliances and far-infrared devices
because of their high temperature strength and strong plasticity.
