摘要： Disclosed is a mixed powder for powder metallurgy containing an iron base powder and a carbon-supplying component, wherein the carbon-supplying component contains a graphite powder and a carbon black, and the mixing ratio between the graphite powder and the carbon black is within the range of graphite powder:carbon black = 25-85 parts by weight:75-15 parts by weight. Also disclosed is a mixed powder for powder metallurgy containing an iron base powder and a carbon-supplying component, wherein the carbon-supplying component mainly contains a carbon black having a dibutyl phthalate absorption of not more than 60 mL/100 g and a nitrogen adsorption specific surface area of not more than 50 m2/g. Each mixed powder for powder metallurgy hardly suffers from dust generation or segregation of the carbon-supplying component. By using such a mixed powder for powder metallurgy, there can be produced a green compact and a sintered compact having excellent mechanical characteristics.
