SOFT MAGNETIC MATERIAL, DUST CORE AND METHOD FOR PRODUCING DUST CORE

摘要

A soft magnetic material has an iron based powder (30) that has an insulating coating (20) on the surface and an ester wax (40). The ester wax (40) is added in an amount not less than 0.02% by weight and not more than 0.6% by weight in relation to the soft magnetic material. Consequently, seizure between a metal mold and a material to be molded at the time of molding can be suppressed and the arising of a black residue can be prevented.
