Zusammenfassung:	The present invention relates to a method of forming a 6xxx or 7xxx series Al alloy blank is provided. The method comprises the steps of heating the blank to a solutionization (SHT) temperature, T SHT , for the alloy of the blank at a heating station and keeping the blank at said SHT temperature until SHT is complete, cooling the blank at a cooling station to an intermediate temperature, T ITM , at which the kinetic movement for the alloy in the blank stops and at a cooling rate that is high enough such that re-crystallization in the alloy of the blank does not occur, forming the blank in a forming tool, quenching the formed blank to room temperature, T E , and artificially ageing the formed and quenched blank in an ageing station. The present invention further relates to a 6xxx or 7xxx series Al alloy blank forming system (1, 3).
