PURPOSE:To obtain a soft magnetic material having superior characteristics in an AC range by mixing powder of a soft magnetic metal or alloy with a prescribed percentage of fluororesin powder, molding the powdered mixture, and sintering it. CONSTITUTION:A powdered mixture is prepared by mixing 95-99.5wt% metallic or alloy powder of <=40 mesh grain size such as powder of pure iron, Fe-Si, ''Sendust'', ''Permalloy'', ''Super Permalloy'', electric ferritic stainless steel or an amorphous magnetic metal with 0.5-5wt% fluororesin powder of <=1mum grain size. The powdered mixture is press-molded or further sintered to surround the particles of the powder of the soft magnetic metal or alloy with the fluororesin. The resulting soft magnetic material has superior magnetic characteristics in an AC range, especially in a high frequency range. |
