  • Product Description

High resistance FeCrAl electric resistance alloy wire.
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.

FeCrAl alloys have higher service temperature than NiCr Alloys and much lower prices. But they have lower stability and flexibility, easily to be fragile after a time circle.
size range:0.01-1.0mm on spool.
high quality and prompt after-sell service,welcome to contact me for more detailed information.
