<p>A magnetic composition to be used as a magnetic core for a transformer or for high-frequency welding of a laminated tube and a process for producing a magnetic molding from the magnetic composition. The magnetic composition comprises 80 to 95 wt % of ferromagnetic powder, 5 to 20 wt % of highly heat-resistant thermosetting resin powder, and 0.1 to 1 wt % of a metal chelate compound. All of these powers are mixed together and molded under heat and pressure to produce a magnetic molding. The composition enables molding of materials of complicated form at low tempertures, and the obtained moldings have excellent heat resistance, mechanical strength, mechanical workability, and initial magnetic permeability.</p> |
