PROBLEM TO BE SOLVED: To provide powder for metallurgy whose moldability can be improved, and which can improve the strength of a molded body upon molding, to provide a powder magnetic core, to provide a method for producing powder for metallurgy, and to provide a method for producing a powder magnetic core. SOLUTION: The powder for metallurgy comprises first powders 10 and second powders, and in which the mass ratio of the second powder to the first powder 10 is 1 to 2.25. The first powder 10 comprises a plurality of first iron base particles 11 and a lubricant 12 covering the surfaces of the plurality of first iron base particles 11, and does not comprise a binder covering the surfaces of the first iron base particles 11. The second powder comprises a plurality of second iron base particles 21 and a binder 22 covering the surfaces of the plurality of second iron base particles 21, and does not comprise a lubricant covering the second iron base particles 21. The lubricant 12 covers the surfaces of the first iron base particles 11. The binder 22 covers the surfaces of the second iron base particles 21. COPYRIGHT: (C)2010,JPO&INPIT |
