  • Resin-bonded magnetic composition and process for producing magnetic molding therefrom
    Patent number: 4808326
    Abstract: A magnetic composition which comprises 80 to 95 weight % of ferromagnetic powder, 5 to 20 weight % of highly heat-resistant thermosetting resin powder and 0.1 to 1 weight % of a metal chelate compound. Further, a process characterized in that all of the powders which comprise the magnetic composition are mixed together and molded under heat and pressure to produce a magnetic molding.The magnetic composition enables molding of materials of complicated form at low temperatures, and the obtained magnetic moldings are excellent in heat resistance, mechanical strength, mechanical workability and initial magnetic permeability.
