Al-Mg-Sc based alloys include additional elements selected from the group comprising Hf, Mn, Zr, Cu and Zn to improve their tensile properties. The alloys are preferably comprised of aluminum and, in wt.%, 1.0-8.0 % Mg, 0.05-0,6 % Sc, 0.05-0.20 % Hf and/or 0.05-0.20 % Zr, and 0.5-2.0 % Cu and/or 0.5-2.0 % Zn. In addition, 0.1-0.8 wt.% Mn may be added to the alloy to improve its strength characteristics further.
