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.
