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.
