Abstract (en)
[origin: EP0342922A2] Fe-based soft magnetic alloy having improved soft magnetic characteristics with high saturated magnetic flux density, characterized in having fine crystal grains and defined by formula (I) Fe100-a-b-cCuaMbYc (I) wherein "M" is at least one element from: groups IVa, Va, VIa of the periodic table, Mn, Co, Ni, Al, and the Platinum group, "Y" is at least one of: Si, B, P, and C, and wherein a, b and c, in atomic % are defined thus: 3 < a</= 8 0.1< b</= 8 3.1</= a+b</= 12 15 </= c </= 28. A dust core made from an alloy powder having fine crystal grains is defined by formula (II) Fe100-a-b-c-d-eCuaM min bM sec cSidBe (II) wherein "M min " is at least one element from: Groups IVa, Va, VIa of the periodic table; "M sec " is at least one element from: Mn, Co, Ni, Al, and the Platinum group; and wherein a, b, c, d and e, in atomic %, are defined thus 3< a</= 8 0.1< b</= 8 0</= c</= 15 8</= d</= 22 3</= e</= 15 15</= d+e </= 28.
