Zusammenfassung: | An aluminium alloy for superplastic aluminium flat products having the following composition: Si≤0.4 wt. %, Fe≤0.4 wt. %, Cu≤0.1 wt. %, 0.5 wt. %≤Mn≤1.0 wt. %, 4.7 wt. %≤Mg≤5.5 wt. %, 0.05 wt. %≤Cr≤0.25 wt. %, Zn≤0.25 wt. %, Ti≤0.20 wt. %, Na≤2 ppm, unavoidable impurities individually ≤0.05 wt. %, in total ≤0.15 wt. %, remainder aluminium. A method for producing an aluminium flat product in which an aluminium melt is provided from the above-mentioned aluminium alloy, in which the aluminium melt is cast to form an ingot, in which the ingot is hot rolled to form a hot strip, in which the hot strip is cold rolled to form a cold strip, and in which the cold strip is levelled. Further disclosed is an aluminium flat product produced by the method and a use thereof. |
