Abstract
A motor vehicle sheet metal molding of the invention is produced by hot forming from a metal sheet composed of an aluminum alloy which cannot be precipitation hardened, which contains at least magnesium and optionally manganese in addition to aluminum as alloy component. The motor vehicle sheet metal molding after forming has, at least locally, degrees of deformation which are above the forming limit curve of the aluminum alloy at room temperature. To produce the motor vehicle sheet metal molding, the metal sheet is heated at least locally to a temperature in the range from 200° C. to 400° C. over a period of from 1 to 60 seconds. The heated metal sheet is subsequently placed in a forming tool of a forming press and formed to produce the motor vehicle sheet metal molding.
