MXPA04007834A - Aluminium diecasting alloy. - Google Patents

Abstract

An aluminium alloy suitable for diecasting of components with high elongation in the cast state comprises, as well as aluminium and unavoidable impurities, 8 .5 to 10.5 w.% silicon, 0.3 to 0.8 w.% manganese, max 0.06 w.% magnesium, max 0.015 w.% iron, max 0.03 w.% copper, max 0.10 w.% zinc, max 0.15 w.% titanium and 0.05 to 0.5 w.% molybdenum. Optionally, the alloy also contains 0.05 to 0.3 w.% zirconium, 30 to 300 ppm strontium or 5 to 30 ppm sodium and/or 1 to 30 ppm calcium for permanent refinement. The alloy optionally contains 0.05 to 0.3 w % circonium and for grain refinement gallium phosphide and/or indium phosphide in a quantity corresponding to 1 to 250 ppm phosphorus and boron added by way of an aluminium master alloy with 1 t o 2 w.% Ti and 1 to 2 w.% B.
