Abstract (en)

New aluminum casting alloy (I) comprises (by weight) 5-11% silicon, 0.1-0.8% magnesium, 0.05-5% silver, at most 0.30% iron, at most 0.20% titanium, at most 2/3 of the iron content of manganese, at most 0.10% zinc and the remainder aluminum, the contents of further impurities being at most 0.03% individually and at most 0.1% in total. An independent claim is included for the production of castings from (I), where the casting is solution annealed, quenched and hot stored.
