Abstract

A Fe-base soft magnetic alloy of formula Fe100-a-b-c-dPaMbM'cCud where M is at least one element selected from Zr, Hf, Nb, Mo, W, Ta, Ti, V, Cr, Mn, Y and Ce; M' is at least one element selected from Si, Al, Ga, Ge, Ru, Co, Ni, Sn, Sb and Pd;
a, b, c and d each are an atomic % and satisfy the relations: 0 < a ≦ 25, 0 < b ≦ 15, 0 ≦ c ≦ 20, and 0 ≦ d ≦ 5 having excellent soft magnetic properties, especially low magnetostriction and low iron loss is made by adding a determined amount of a specific element M, a determined amount of Cu is further added to the alloy and the quenched alloy composition is shaped and heat-treated to provide the Fe-base soft magnetic alloy.
