Abstract Fe-Cu-Mo-C alloys were prepared by mechanical milling and vacuum sintering. The effect of sintering temperature on the microstructure， density， tensile strength， friction and wear properties of the Fe-based powder metallurgy Fe-Cu-Mo-C was studied. Results show that the pores reduce and its size decreases when sintering temperature increases from 1 000 ℃ to 1 100 ℃； while the pore size increases when sintering temperature increases to 1 150 ℃. The relative density， hardness， tensile strength and elongation of the sintered body increase firstly and then decrease with the increase of sintering temperature. The mass wear of as-sintered sample decreases firstly and then increases with the increase of sintering temperature. The optimum performance is obtained for samples sintered at 1 100 ℃， with sintered density of 6.90 g/cm3， tensile strength of 319 MPa， hardness of 34.7 HRC and mass loss of 0.087 g.
