Feature:
With long service life.Heating up fast.High thermal efficiency.Temperature uniformity. Can use vertically. When being used in the rated voltage,there is no volatile matter.It is an environmental protection electric heating wire. And an alternative to the costly nichrome wire.Can be customized according to customer requirements
FeCrAl alloys are characterized by excellent oxidation resistance and very good form stability resulting in long element life.
They are typically used in electrical heating elements in industrial furnaces and home appliances.
Fe-Cr-Al alloy with high resistivity and serviceability temperature than that for NiCr alloy and also has lower price.
