摘要

Part of the same composite material made of a thermoplastic plastic matrix with an embedded soft magnetic particles of an alloy which has the composition of the form of (fe_1-aM_a)_{100 - x - y - z - α}Cu_xSi_yB_zM'_α , m being cobalt and / or nickel and m 'of at least one of the elements nb, w, ta, zr, hf, ti and mo is, as well as a, x, y, z and α, in each case, the condition 0 ≦ a ≦ 0,5, 0,1 ≦ x ≦ 3, 0 ≦ y ≦ 30, 0 ≦ z ≦ 25, 5 ≦ y + z ≦ 30, and 0,1 ≦ α ≦ 30, and wherein at least 50% of the alloy particles have a nano-crystalline structure, characterized in that the composite body is formed by injection molding and soft magnetic particles having a thickness of 5 to 50, and cross-sectional areas of 0,05 to 10 mm² the _ proportion by volume (degree of filling) of the soft magnetic particles, based on the total volume 40 to 65 vol.%, and the that the composite body start permeabilities in the case of 10 khz, of at least 30 has.
