Abstract (en)

[origin: EP1997924A1] Cold-hardening aluminum alloys with good heat resistance, useful for producing components subject to thermal and mechanical stress, contain (wt%): silicon 11.0 - 12.0; magnesium 0.7 - 2.0; manganese 0.1 - 1; iron 1 max; copper 2 max; nickel 2 max; chromium 1 max; cobalt 1 max; zinc 2 max; titanium 0.25 max; boron 40 ppm max; and optionally 80 - 300 ppm strontium, the remainder being aluminum and impurities in an amount individually of 0.05 wt% max and 0.2 wt% in total. Independent claims are included for: (A) use of the alloys for casting components subject to thermal and mechanical stress; and (B) castings produced from the alloys.
