Abstract：Cu-Sn powders were prepared by pre-mix and pre-alloy process, the microstructure and phase changes
of Cu-Sn alloy were studied after sintering, and the sintering properties of Cu-Sn powders prepared by these two
methods were tested and compared. The experimental results show that the microstructure of pre-mixing CuSn10
and CuSn20 is composed of α phase and α + δ eutectic tissue after sintering, while that of pre-alloy CuSn10 is α
phase. After sintering, the pre-mixed Cu-Sn green compacts expand, on the contrary the pre-alloyed green com‐
pacts shrinkage. In addition, the strength, oil content and effective oil content of the pre-alloyed Cu-Sn parts are
higher than those prepared by the pre-mixing method.
