ABSTRACT:
An aluminum-alloy main-starting powder for producing a sintered aluminum-alloy consists of from 0.1 to 3.0% of Cu, the balance being Al and unavoidable impurities. Mother alloy powder consists of from 4 to 20% of Mg, from 12 to 30% of Si, and Al and unavoidable impurities in balance. A mixture of the two powders may also be produced. Further, from 0.2 to 2.0% of a lubricant may be added to the mixture.
