Nickel-chromium and nickel-chromium-iron alloy wire
Nickel-chromium and nickel-chromium-iron alloys are the most widely used high-resistance electric heating alloys. The alloy has high resistivity, good oxidation resistance and wear resistance, good machinability and weldability. have higher strength. The alloy is suitable for the manufacture of heating elements in metallurgy, chemical industry, machinery, glass, ceramics and household appliances, as well as voltage regulating resistors and braking resistors for various motors.
