PCT No. PCT/GB96/02010 Sec. 371 Date Apr. 14, 1997 Sec. 102(e) Date Apr. 14, 1997 PCT Filed Aug. 16, 1996 PCT Pub. No. WO97/06908 PCT Pub. Date Feb. 27, 1997A method of manufacturing a cylinder block comprising one or more cylinders, the or each cylinder being adapted to receive a piston therein, the method comprising making a cylinder liner by squeeze casting, in an aluminium-silicon alloy produced from a melt consisting essentially of the following composition by weight: Silicon 14% to 16%; Copper 1.9% to 2.2%; Nickel 1.0% to 1.4%; Magnesium 0.4% to 0.55%; Iron 0.6% to 1.0%; Manganese 0.3% to 0.6%; Silicon Modifier 0.02% to 0.1%, with the balance being aluminium and any avoidable impurities, the cylinder liner having an essentially eutectic microstructure containing not more than 10% primary alpha-aluminium dendrites and being substantially free from intermetallic particles exceeding 10 mu in diameter, placing the cylinder block in a mold and casting therearound an aluminium alloy to provide a main cylinder block body with the cylinder liner entrapped therein.
