Aluminium alloys

摘要

An aluminium alloy made by a powder metallurgy route and a method for its production are described. The method comprises the steps of producing a first powder of a near-eutectic aluminium-silicon based alloy; producing a second powder of a hypereutectic aluminium-silicon based alloy; mixing desired proportions of the two powders together, compacting the powder mixture and sintering the compacted powder.
