    FeCrAl alloy 0Cr27Al7Mo2 CrAl high temperature resistance Alloy Resistance Wire (Working Temperature 1400C )

    FeCrAl alloy is high resistancec and electrical heating alloy. Fecral alloy can reach process temperature of 2192 to 2282 F,corresponding to a resistance temperature of 2372F.

    In order to improve anti-oxidation ability and increase working life, we usually put addition of rare earths in the alloy, such as La+Ce,Yttrium, Hafnium,Zirconium,etc.

    It is normally used in electrical furnace, glass top hobs,quartz tube heaters, resistors,catalytic converter,heating elements etc.
