Low MOQ 0Cr21Al16Nb FeCrAl alloy heating electric wire
Fe-Cr-Al Alloy Grade : 1Cr13Al4, 0Cr15Al5, 0Cr23Al5, 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2,0Cr21Al6
0Cr21Al16Nb FeCrAl alloy heating electric wire 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.
0Cr21Al16Nb FeCrAl alloy heating electric wire 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.
