| titleOfInvention | Magnetic powder, manufacturing method of magnetic powder and bonded magnets |
| abstract | The present invention relates to providing a magnet having excellent magnetic properties and high reliability, particularly a magnet having excellent thermal stability. The magnet powder of the present invention is R x (Fe 1-a Co a ) 100-xyz B y M z (where R is at least one rare earth element except Dy, M is Ti, Cr, Nb, V, Mo, At least one of Hf, W, Mn, Zr, and Dy, x is 7.1 to 9.9 atomic%, y is 4.6 to 8.0 atomic%, z is 0.1 to 3.0 atomic%, and a is 0 to 0.30) A magnetic powder composed of an alloy composition represented by the present invention, which is composed of a composite structure having a hard magnetic phase and a soft magnetic phase, and mixed with a binder resin to be injection molded or extruded to form a bonded magnet having a density ρ [Mg / m 3 ]. When the maximum magnetic energy product (BH) max [kJ / m 3 ] at room temperature satisfies Equation 1 below, the intrinsic coercive force (H CJ ) at room temperature is 400 to 760 kA / m. to be. |
