SOFT MAGNETIC ANISOTROPIC COMPOSITE MATERIALS

摘要

The invention concerns a soft magnetic, anisotropic composite material essentially consisting of compacted, essentially flaky shaped, electrically insulated particles of essentially pure iron powder containing less than 0.01 % by weight of carbon, which particles are aligned in essentially parallel relationship and bonded together by an organic polymer resin. The new material is characterized by a green density of at least 7.4 g/cm<3>. The invention also concerns a process for the preparation of the new material as well as the use of the material for devices operating at power frequencies.
