Iron-chromium-aluminium (FeCrAl) alloysFeCrAl 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 then NiCr Alloys and much lower prices. But they have lower stability and flexibility, easily to be fragile after a time circle.Main grades and properties0Cr21A16Chemical composition %Cr19.0-22.0Al5.0-7.0FeBalanceOtherHighest service temperature ℃1250ResistivityμΩ.m,20℃1.42Density (g/cm3 )7.16Thermal conductivity KJ/m.h.℃63.2Coefficient of linear extensibility α×10-6/℃14.7Melting point ℃1500Tensile Mpa630-780Elongation %>12Reduction %65-75Hardness H.B.200-260MicrostructureFerriteMagnetic propertymagnetic
