| Abstract: | Cu-Zn-Fe alloy powders were prepared by different diffusion techniques and the powders physical properties were tested.The results show that loose density,fluidnity and grain finensize distribution of the powders were mainly affected by particle structure and morphology.The influence of diffusion tempreture and time on powder physical properties is explained with powder sintering theory. |

| Keywords: | diffusion technique copper alloy powder loose density flowrate |
