PCT No. PCT/GB94/01180 Sec. 371 Date Nov. 30, 1995 Sec. 102(e) Date Nov. 30, 1995 PCT Filed May 31, 1994 PCT Pub. No. WO94/29489 PCT Pub. Date Dec. 22, 1994An 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.
