ISO Certified KD FeCrAl Alloy Round Bar / Rod With Acid Surface Used For Electrical Heating Leading Bar
Tankii DESCRIPTION OF FECRAL ALLOYS: KD alloys, Alchrome /
Aluchrome I / KD / KDS
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
