Fe-Al alloys contain 6% to 16% aluminum , the rest elements is the iron. The alloys have high resistivity, lower density and higher hardness of soft magnetic alloy. This family of alloy is suitable for the special environment (such as nuclear radiation, shock, acceleration, etc.), and resistance to corrosion and oxidation resistance are better than those of nickel-iron&soft magnetic alloys, and silicon steel.
Forms: Sheet/Plate, Bar/Rod/Wire/Coil

Description

Fe-Al alloys contain 6% to 16% aluminum , the rest elements is the iron. The alloys have high resistivity, lower density and higher hardness of soft magnetic alloy. This family of alloy is suitable for the special environment (such as nuclear radiation, shock, acceleration, etc.), and resistance to corrosion and oxidation resistance are better than those of nickel-iron&soft magnetic alloys, and silicon steel.

Application

Fe-Al alloys have accessed to a broad industrial application in the fields of aviation, space flight, navigation, and other civilian and military industries.
