FeCrAl Resistance Wire Description
FeCrAl Resistance Wire features a high rate of resistance, small resistance temperature coefficient, and high use temperature. It has good corrosion resistance at high temperatures, especially in the atmosphere of sulfur and sulfide. Therefore, it is an ideal heating material used in industrial furnaces, household appliances, and far-infrared devices.
