PROBLEM TO BE SOLVED: To provide an Fe-based alloy composition that can achieve low coercive force of 8.0(A/m) or less and obtain high soft magnetic properties.SOLUTION: An Fe-based alloy composition is constituted by following compositions in atom%, B:3.0 to 6.0%, Si:≤8.0%, P:4.0 to 8.0%, Cu:0.3 to 1.0%, C: more than 5.0 to 12.0%, Fe in remained portions and unavoidable dopant. Preferably, the Fe content is 77 to 84%. |
