China Cr25al5 Resistohm Y Aluchrom Y

Resistohm Y High TemperaIndustrial Customized Service ture Heating Resistance Fecral Alloy Strip

General Description
FeCrAl alloy is made by a high-temperature, ferritic iron-chromium-aluminium alloy which can be used at temperatures up to 1350degrees. Typical applications for 0Cr21Al6Nb are as electrical heating elements in high-temperature furnaces in the heat treating, ceramics, glass, steel, and electronics industries.

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 volatileDrying Machine matter.It is an environmental protection electric heating wire. And aWatch Box n alternative to the costly nichrome wire.Can be customized according to customer requirementsFeCrAl 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.
