1.Nichrome, Nichrome
Nickel-chromium and nickel-chromium-iron alloys have high and stable resistivity, corrosion resistance, good surface oxidation resistance, good seismic strength at high temperatures, good properties, good processability and weldability, and are widely used in Industrial electric furnace, metallurgy, household appliances, machinery manufacturing, heating elements and resistor rheostats, etc.
2.Iron chromium aluminum alloy
It is a high-resistance alloy material, which has the advantages of high resistivity, small temperature coefficient of resistance, long temperature resistance, long life, light weight, and cheap price. It is especially suitable for use in sulfur and sulfide-containing atmospheres. It is an industrial electric furnace, household appliances, Ideal heating material in infrared heating device.
