Patent ·
OSTI ID:5285039
An engine block is described for an internal combustion engine, comprising a cast block composed of a hypereutectic aluminium silicon alloy and having at least one cylinder bore therein. The alloys consists essentially of 16% to 19% by weight of silicon, 0.4% to 0.7% by weight of magnesium, up to 1.4% by weight of iron, up to 0.3% by weight of manganese, up to 0.37% by weight of copper, and the balance aluminium. The alloy has excellent fluidity, a solidification range of less than 150/sup 0/ F., and has a weight loss of less than 1.0% when exposed for 200 hours at ambient temperature in a 5% sodium chloride solution.
