摘要
This invention concerns production by extrusion of hollow cylindrical bodies starting with granulated alloys of aluminum containing silicon. It consists of preparing the composition of the alloy in a liquid form, producing granules by centrifugal pulverization or atomization, introducing the granulated material into an extrusion press to obtain the hollow profile by extrusion and extruding the granular material within to form a cylindrical body. This invention is applicable to form hollow bodies and particularly sleeves of motors of high content silicon aluminum alloy through which size and distribution of primary silicon is improved over traditional casting methods.
