Abstract (en)
[origin: EP0796926A1] An aluminum-silicon eutectic type casting material containing 7.5 to 12 wt% of silicon and at least one of 1.5 to 4.8 wt% of copper and 0.2 to 0.7 wt% of magnesium is cast by a high speed die casting method. After mold release, the resulting die cast product is subjected, after the surface temperature thereof falls to within the range of 250 to 450 DEG C, to at least one of a water cooling treatment which immerses the die cast product into a water tank and an ageing treatment which retains it at a temperature within the range of 150 to 250 DEG C for a predetermined time.
