ABSTRACT:
Process for manufacturing sintered compacts of aluminum-base alloys having contents of Si, Cu and Mg, which comprises, mixing an aluminum powder and/or an Al-Si alloy powder with at least one powder of Al-Cu-Mg-Si, Al-Cu-Mg and so on in such a proportion, that the former will amount to 70% or more, based on the total weight of the resulting powder mixture, and that the over-all composition of the resulting powder mixture will lie essentially in the range of 1.0.about.6.0% by weight of Cu, 0.2.about.2.0% by weight of Mg, 0.2.about.2.0% by weight of Si and rest of Al, compacting the so obtained powder mixture into shapes and then sintering the so obtained green compacts in the air.
