A higher content of aluminum in magnesium alloys leads to the formation of the precipitation hardening intermetallic compound Mg17Al12. However, the rollability and the resulting ductility and formability of sheets of such alloys are reduced with increasing Al content. In this study, magnesium alloys of the AZ- and AM- series were used to investigate the impact of the aluminum content on the rollability, the resulting sheet properties and the precipitation strengthening of the sheets subsequent to the rolling process. Alloys with 6 wt.% and 8 wt.% aluminum were used. The higher content of aluminum leads to a decrease of rollability as well as a decrease of the ductility of the sheets after rolling and annealing. Alloys of the AM series perform more advantageous compared to AZ series alloys. However, Mn limits the ability to precipitation strengthening. The ability to balance both properties is discussed.
