1. An aluminium alloy consisting of:
3.0 to 6.0% by weight, in relation to the total weight of the alloy, of magnesium (Mg), >1.0 to 4.0% by weight, in relation to the total weight of the alloy, of silicon (Si), 0.005 to 0.2% by weight, in relation to the total weight of the alloy, of titanium (Ti), 0.1 to 0.75% by weight, in relation to the total weight of the alloy, of scandium (Sc), 0.01 to 0.375% by weight, in relation to the total weight of the alloy, of zirconium (Zr), 0 to 0.5% by weight, in relation to the total weight of the alloy, of at least one element selected from the group consisting of hafnium (Hf), molybdenum (Mo), terbium (Tb), niobium (Nb), gadolinium (Gd), erbium (Er), and vanadium (V), 0 to 0.8% by weight, in relation to the total weight of the alloy, of manganese (Mn), 0 to 0.3% by weight, in relation to the total weight of the alloy, of chromium (Cr), 0 to 1.0% by weight, in relation to the total weight of the alloy, of copper (Cu), 0 to 0.05% by weight, in relation to the total weight of the alloy, of zinc (Zn), 0 to 0.6% by weight, in relation to the total weight of the alloy, of iron (Fe), 0 to 0.004% by weight, in relation to the total weight of the alloy, of beryllium (Be), and the rest being aluminium with further impurities individually of at most 0.1% by weight in relation to the total weight of the alloy, and on the whole at most 0.5% by weight, in relation to the total weight of the alloy, wherein the amount of zirconium (Zr) and of titanium (Ti) in total corresponds at most to half the amount of scandium (Sc). |
