Abstract:
The present disclosure relates to a method for producing a motor vehicle component from a 6000-series aluminum alloy having the following method steps: providing a blank made of a 6000-series aluminum alloy, rapid heating of the blank by means of contact plates to a temperature between 450° C. and 600° C. in a time less than 20 seconds, ending of the heating procedure and optional homogenizing when a grain size between 20 and 50 μm has resulted, quenching the blank thus tempered to a temperature less than or equal to 100° C., in a time less than 20 seconds, wherein the rapid heating and quenching of the blank is carried out in a total time of less than 50 seconds, applying a lubricant, at 20° C. to 100° C., forming the cooled blank in a forming tool, wherein the time between beginning the rapid heating and beginning the forming is less than 45 seconds, aging.
