This paper presents the recycling of aluminum chips by hot extrusion as an alternative to re-melting. Three different types of chips were produced from aluminum alloy 6060 material and then compacted into extrusion billets and hotextruded at 500 deg C to full 5 x 20 mm2 rectangular profiles. The tensile strength of the extruded profiles produced from the chips was on average 10% lower than the values of extruded profiles from as-cast material. In the case of one chip type an even higher ductility was achieved, which can be attributed to the density of the chip boundaries acting like grain boundaries. Also, the influence different chip types have on the machinability of the extruded profiles was investigated.
