Abstract Atomized Cu-Sn50 alloy powder with low melting point and high Sn content were prepared by hot pressing test. The effects of sintering temperature， holding time and holding pressure on the sintering properties of the powder were studied using orthogonal test method. Through the range analysis of orthogonal test data， the SEM morphology of the test sample and the observation and analysis of the microstructure， the sintering properties of the samples were measured and the optimal test scheme was obtained. The results show that the Cu-Sn50 alloy powder has good performance at the sintering temperature of 440 ℃， the dwell time of 180 s and the pressure of 10 MPa.
