Resistance Wire (FeCrAl) - 0Cr21Al6Nb

Resistance Wire (FeCrAl) - 0Cr21Al6Nb
Product Detailed
1.High rate of resistance, small resistance temperature coefficient 2.have a good corrosion resistance Our resistance wire(heating wire) 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.Main characteristics of FeCrAl high resistance and heating alloys
