| Message: | 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 properties0Cr21A16NbChemical composition %Cr21.0-23.0Al5.0-7.0FeBalanceOtherNb 0.5Highest service temperature ℃1350ResistivityμΩ.m,20℃1.45Density (g/cm3 )7.10Thermal conductivity KJ/m.h.℃46.1Coefficient of linear extensibility α×10-6/℃16.0Melting point ℃1510Tensile Mpa650-800Elongation %>12Reduction %65-75Hardness H.B.200-260MicrostructureFerriteMagnetic propertymagnetic url:http://www.nichromalloy.com |
