A high Si aluminum alloy powder was prepared by ultrasonic gas atomization process. The morphology and size distribution characteristics of the alloy powder were observed by means of SEM and mechanical vibration method systematically. The results showed that the powder prepared by ultrasonic gas atomization has relatively uniform size distribution ranging from 40 to 100 μm. The morphology characteristics is related to the powder size. With decrease in size the morphology became regular more and more.
