Abstract
An age-hardenable aluminum alloy on the basis of Al—Mg—Si, Al—Zn, Al—Zn—Mg or Al—Si—Mgv has precipitates caused by natural aging. The aluminum alloy has at least one alloy element, in addition to its main alloy element or in addition to its main alloy elements, which can be correlated with quenched-in empty spaces of the aluminum alloy, particularly reducing their mobility in the crystal lattice, at such a content less than 500, particularly less than 200 atomic ppm, that the aluminum alloy forms empty spaces essentially not correlated with these precipitates, in order to reduce the negative effect of natural aging of the aluminum alloy on its further artificial aging, by mobilization of these non-correlated empty spaces.
