PURPOSE: To provide bonded magnet material which is stable in magnetic properties against temperature change and restrained from increasing in manufacturing cost, a molded body formed thereof, and a static convergence device equipped with the molded body. CONSTITUTION: Magnetic powder mixture composed of 50 to 60 weight% of alnico metal material powder (Al: 5 to 10weight%, Ni: 10 to 30weight%, Co: 0 to 40weight%, Ti: 0 to 5 weighty, Cu: 1 to 10-weight%, and Fe: residual %) and residual weight% of barium ferrite powder and/or strontium ferrite powder and organic binder are heated and kneaded together, whose temperature coefficient is set to -0.1%/ deg.C to 0%/ deg.C. |
