0Cr27Al7Mo2 FeCrAl Alloy For Electrical Heating Elements Bright Surface
0Cr27Al7Mo2 FeCrAl Alloy for Electrical Heating Elements and Industrial Furnaces
0Cr27Al7Mo2
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.
Fe-Cr-Al alloy with high resistivity and serviceability temperature than that for NiCr alloy and also has lower price.
Forms:wire, bar, strip,sheet/plate,forging,tube/pipe,etc.
