Abstract

PURPOSE: Permanent magnet having an excellent mechanical strength and high energy product, obtained by mixing a specific quantity of Sm-Co-Fe-Zr type magnetic compound of Sm2(Co, Cu, Fe, Zr)17 phase limited the volume coefficient after heat treatment, with liquid epoxy resin etc.
CONSTITUTION: Sm-Co-Fe-Zr type powdered magnetic compound composed of Sm2(Co, Cu, Fe, Zr)17 phase being volume coefficient more than 90% after heat treatment, is mixed with liquid epoxy resin having 200W20000 cp of vixcosity, so as the volume coefficient to be 65W90%. Next, the above mixture is baked and magnetized after forming in magnetic field. Grain diameter of more than 90% of the abobe powdered magnetic compound, is necessary to be 3W50μ.
