Abstract (en)

The aluminum alloy for die casting, especially with high ductility and expansion in the casting condition for the automotive industry, incorporates selectively 0.05-0.3 wt.% zirconium, 30-300 ppm of strontium or 5-30 ppm of sodium and/or 1-30 ppm of calcium for durable refinement of gallium phosphide and/or indium phosphide in a volume to give 1-250 ppm of phosphorus for granular refinement, and titanium and boron introduced into aluminum pre-alloy, with 1-2 wt. % titanium and 1-2 wt.% boron, for grain refining : The aluminum alloy incorporates (in wt.%) 8.0-11.5 silicon, 0.08-0.4 magnesium, 0.3-0.8 manganese, =0.1 iron, =0.1 copper, =0.1 zinc, =0.15 titanium, =0.05-0.5 molybdenum, and =0.05-0.3 zirconium.
