A mixed powder for powder metallurgy

PROBLEM TO BE SOLVED: To provide a mixed powder for powder metallurgy which allows reduction of variation of the weight of a molding by improving the packing capacity of a mold.SOLUTION: A mixed powder for powder metallurgy is obtained by mixing a graphite powder of an average particle size D50 of 1.0-3.0 μm and an average particle size D90 of 10 μm or smaller with an iron-based powder under shear force, without addition of a binder. The mixed powder for powder metallurgy thus obtained contains an iron-based powder and a graphite powder present collectively in concave parts of the iron-based powder.
