Fe Based Amorphous Alloy And Fe Based Amorphous Alloy Thin Strip

Abstract: The purpose of the present invention is to provide: an Fe-based amorphous alloy which has low iron loss, high saturation magnetic flux density, and excellent soft magnetic characteristics; and an Fe-based amorphous alloy thin strip. An Fe-based amorphous alloy having excellent soft magnetic characteristics according to the present invention is characterized by containing, in terms of at%, 8.0-18.0% of B, 2.0-9.0% of Si, 0.10-5.00% of C, 0.005-1.50% of Al, 0-1.00% (exclusive of 1.00) of P, 0-0.30% of Mn, and 78.00-86.00% of Fe, with the remainder consisting of impurities, wherein the structure of the Fe-based amorphous alloy is amorphous.
