The diecasting alloy based on aluminium-silicon contains 9.5 to 11.5 w.% silicon 0.1 to 0.5 w.% magnesium 0.5 to 0.8 w.% manganese max 0.15 w.% iron max 0.03 w.o copper max 0.10 w.% zinc max 0.15 w.% titanium with the remainder aluminium and for permanent refinement 30 to 300 ppm strontium. The alloy is particularly suited for diecasting safety components such as car wheels for example.
