ABSTRACT OF THE DISCLOSURE A powder mixture used for powder metallurgy containing a metal powder as a substrate, in which a copolymer com- prising the following monomer ingredients as a binder is blended: acrylic acid ester : 20 to 70 parts by weight methacrylic acid ester : 80 to 30 parts by weight polymerizable unsaturated acid : 0.5 to 9 parts by weight based on 100 parts by weight of the sum for the acrylic ester and the methacrylic acid ester, as a binder is blended therewith. The powder mixture used for powder metallurgy is manufactured by mixing the starting powdery metal material with the starting powdery material for the physical property improving ingredient, adding the solution of the binder thereto and then applying stirring and drying. Graphite segregation can be prevented without de- naturingor reducing flow rate of the substrate metal or dusting upon handling can be suppressed.
