Abstract (en)
[origin: EP0918095A1] A structural component of a die cast aluminum alloy, which contains 0.05-0.4 wt.% Sc and optionally 0.1-0.4 wt.% Zr. Preferred Alloys: The aluminum alloy has the composition (by wt.) NOTGREATER 0.5% Si, NOTGREATER 1.0% Fe, 0.1-1.6% Mn, NOTGREATER 5.0% Mg, NOTGREATER 0.3% Ti, NOTGREATER 0.1% Zn, 0.05-0.4% Sc, optionally 0.1-0.4% Zr, balance Al and NOTGREATER 0.2% total ( NOTGREATER 0.02% each) impurities. The especially preferred composition is (a) 0.1-0.8 (especially 0.15-0.25)% Si, 0.2-0.8 (especially 0.5-0.7)% Fe, 0.5-1.8 (especially 1.2-1.4)% Mn, NOTGREATER 1.5% Mg, NOTGREATER 0.3% Ti, NOTGREATER 0.1% Zn, 0.05-0.4 (especially 0.05-0.2)% Sc, optionally 0.1-0.4 (especially 0.1-0.2)% Zr, balance Al and NOTGREATER 0.2% total ( NOTGREATER 0.02% each) impurities; or (b) 0.05-1.0 (especially 0.15-0.25)% Si, 0.05-0.2 (especially NOTGREATER 0.15)% Fe, 0.5-1.8 (especially 0.8-1.0)% Mn, 2.0-4.5 (especially 2.5-3.5)% Mg, NOTGREATER 0.2% Ti, NOTGREATER 0.1% Zn, 0.05-0.4 (especially 0.05-0.2)% Sc, optionally 0.1-0.4 (especially 0.1-0.2)% Zr, balance Al and NOTGREATER 0.2% total ( NOTGREATER 0.02% each) impurities.
