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.
Application area
Our products are widely used in heat treatment equipment, auto parts, iron and steel manufacturing,
aluminum industry, metallurgical equipment, petrochemical equipment, glass machinery, ceramic machinery,
food machinery, pharmaceutical machinery, and power engineering industry.
