Abstract

A method for producing a motor vehicle component, is disclosed having the steps of—providing a blank composed of a 5000 grade naturally hard aluminum alloy with an initial yield strength, completely heating the blank to a forming temperature between 150° C. and 350° C., preferably between 200° C. and 300° C. in less than 20 s, preferably less than 10 s and in particular in 2 to 5 s, and performing forming in a forming tool in less than 20 s, preferably less than 10 s and in particular between 2 and 5 s, the temperature being held between 150° C. and 350° C. in at least one first region of the blank, and cooling to a temperature lower than 250° C., in particular lower than 200° C., being performed in a second region during or after the deformation.
