High Temperature Resistance Electrothermal Alloy FeCrAl Alloy 0Cr15Al5 Wire / Flat Wire / Ribbon / Strip / Coil Strip

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 properties1Cr13A140Cr25A150Cr21A160Cr23A150Cr21A140Cr21A16Nb0Cr27A17Mo2Chemical composition %Cr12.0-15.023.0-26.019.0-22.022.5-24.518.0-21.021.0-23.026.5-27.8Al4.0-6.04.5-6.55.0-7.04.2-5.03.0-4.25.0-7.06.0-7.0FeBalanceBalanceBalanceBalanceBalanceBalanceBalanceOtherNb 0.5Mo1.8-2.2Highest service temperature ℃950125012501250110013501400ResistivityμΩ.m,20℃1.251.421.421.351.231.451.53Density (g/cm3 )7.47.107.167.257.357.107.10Thermal conductivity KJ/m.h.℃52.746.163.260.246.946.145.2Coefficient of linear extensibility      α×10-6/℃15.416.014.715.013.516.016.0Melting point ℃1450150015001500150015101520Tensile Mpa580-680630-780630-780630-780600-700650-800680-830Elongation %>16>12>12>12>12>12>10Reduction %65-7560-7565-7565-7565-7565-7565-75Hardness H.B.200-260200-260200-260200-260200-260200-260200-260MicrostructureFerriteFerriteFerriteFerriteFerriteFerriteFerriteMagnetic propertymagneticmagneticmagneticmagneticmagneticmagneticmagnetic
