Description
High resistance electrothermal alloy
Nichchromium and nichchromium alloy are widely used in high resistance electric heating alloys, with high resistivity, good oxidation resistance and wear resistance, good machining performance and welding performance, high strength at high temperature. Applicable to metallurgy, chemical industry, machinery, glass, ceramics and household appliances and other industrial sectors manufacturing heating components.
Main performance:
