Iiron-Chrome-Aluminium resistance electrical heating alloy has such specialties as high resistivity, small resistance temperature quotiety and high use temperqture. Under high temperature, with good corrosion stability, it is especially applicable to work in the air with sulfur and sulfide. The price is reasonable, so it is the ideal heating material used for industrial electric stove, household appliances and far-infrared devices﹝
