This study was carried out to aim development of new system to recycling waste cans of aluminum using friction extrusion to solve social requirement. The principle is characterized that rotating rod is applied axial load onto the scraped aluminum, which is filled in a cartridge with extruding nozzle. As this process is defined as the solid phase technique, frictional heat and pressure generate relative motion to plastized metal without an external heat source such as furnace heat. Scrap material is extruded into wire form through the cartridge nozzle after continuous generation of the plastized metal flow. The result shows rotation speed of rod and frictional pressure give a significant effect on amount of extruding products and material temperature reaches 829K in processing, which is below melting point of aluminum
