Details :

                              FeCrAl alloy 0Cr23Al5 resistance heating element electric wire                                            

 

Fe-Cr-Al Alloy Grade : 1Cr13Al4, 0Cr15Al5, 0Cr23Al5, 0Cr25Al5, 0Cr21Al6Nb, 0Cr27Al7Mo2,0Cr21Al6

 

FeCrAl 0Cr23Al5alloys 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 0Cr23Al5alloys 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.
