发明名称 MATERIAL FOR BOND MAGNET FORMATION AND BOND MAGNET
摘要 PROBLEM TO BE SOLVED: To provide: a material for bond magnet formation which includes rare earth-iron-nitrogen based magnetic powder, a thermoplastic resin and a silane coupling agent, has high fluidity and good moldability; and a bond magnet having a superior coercive force iHc and a superior squareness ratio (Hk/iHc).SOLUTION: A material for bond magnet formation comprises a composition including rare earth-iron-nitrogen based magnet powder having an average particle diameter (D50) of 1.9 to less than 3.0 μm, and magnetic properties, i.e. a coercive force (iHc) of 880 kA/m or larger, and a squareness ratio (Hk/iHc) of 50% or more, a thermoplastic resin, and a silane coupling agent, of which the fluidity at a heating temperature of 250°C is 1150 g/10 min or larger.SELECTED DRAWING: None
