SOFT MAGNETIC MEMBER AND INTERMEDIATE THEREOF, METHODS RESPECTIVELY FOR PRODUCING SAID MEMBER AND SAID INTERMEDIATE, AND ALLOY FOR SOFT MAGNETIC MEMBER

A soft magnetic member according to the present invention is characterized by having an alloy composition comprising, in % by mass, 5.00 to 25.00% of Co, 0.10 to 2.00% of Si, 0.10 to 2.00% of Al (wherein the total amount of Si and Al is 1.00 to 3.00%), and a remainder made up by Fe and unavoidable impurities, and having an average crystal grain diameter of 40 µm or more and a core loss of 150 W/kg of less at 1.5 T and 1 kHz. The soft magnetic member can be manufactured by recrystallization induced by a working strain introduced by a cold working and a thermal treatment of the working strain. The present invention can provide: an alloy for an Fe-Co-based soft magnetic member, in which the amount of Co to be added to Fe is controlled and another element is added and thereby has excellent manufacturability without deteriorating the cold workability thereof, and which can satisfy magnetic properties required for use as a soft magnetic member; a soft magnetic member; an intermediate for the soft magnetic member; and methods respectively for producing the soft magnetic member and the intermediate.
