The invention relates to an aluminum alloy, to the use of an aluminum alloy strip or sheet, and to a method for producing an aluminum alloy strip or sheet. The aim of providing an aluminum alloy that has only a slight tendency toward intercrystalline corrosion, provides high strength and good formability at the same time, and contains standard alloy components so that the recycling of the aluminum alloy is simplified, is achieved by an aluminum alloy that has the following composition in wt%: 2.91% < Mg < 4.5%, 0.5% < Mn < 0.8%, 0.05% < Cu < 0.30%, 0.05% < Cr < 0.30%, 0.05% < Zn < 0.9%, Fe < 0.40%, Si < 0.25%, Ti < 0.20%, the remainder Al and contaminants individually less than 0.05%, in total no more than 0.15%, wherein the following applies to the alloy components Zn, Cr, Cu, and Mn: (2.3* %Zn + 1.25* %Cr + 0.65* %Cu + 0.05* %Mn) + 2.4 > %Mg. |
