electric resistance wire,iron chromium aluminium alloy wire,high temperature heating wire

The iron-chromium high electric resistance alloy has the characteristics of high rate of resistance, small resistance temperature coefficient and high use temperature. It has a good corrosion resistance at high temperature, low price and is particularly suitable for using in the atmosphere of sulfur and sulfide, so it is an ideal heating material used in industrial furnaces, household appliances and far-infrared devices.
