0Cr25AL5 FeCrAl resistance heating wire
Iron-chromium-aluminium (FeCrAl) alloys
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 then NiCr Alloys and much lower prices.But they have lower stability and flexibility, easily to be fragile after a time circle.
