COMPOSITE MAGNETIC MATERIAL

摘要

Disclosed is a composite magnetic material which is obtained by press molding a metal magnetic powder to which a binder has been added. The binder contains an acrylic resin that has a silyl group as a functional group. The composite magnetic material may be heat-treated at a temperature of 700-1000°C in a non-oxidizing atmosphere after the press molding. The composite magnetic material can be small-sized, is usable in high-frequency regions, and has adequate magnetic characteristics. Consequently, the composite magnetic material is useful for electromagnetic components such as inductors, choke coils and transformers.
