Abstract The influence of diverse technological parameters on the performanceand structure of product extruded from the atomized Al granule has been studiedon a 250 CONFORM continuous extrusion machine. The favourable extruding tem-perature is 350--450℃. The extrusion ratio is greater than 20. The finer the Algranule is, the better the mechanical properties of the product are. It may be im-proved over 50% in comparison with that from rod feed.
