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.

Abstract: An aluminum alloy and a method for improving the ability of a semi-finished or finished product to age artificially, includes an age-hardenable aluminum alloy on an Al—Mg—Si, Al—Zn, Al—Zn—Mg or Al—Si—Mg basis, wherein the aluminum alloy is transformed to a solid solution state, in particular by solution heat treatment (1), is quenched and subsequently forms precipitations by a process of natural aging (3), the method involving at least one measure for reducing a negative effect of natural aging (3) of the aluminum alloy on artificial aging (4) thereof. In order to achieve advantageous method conditions, a measure for reducing the negative effect involves an addition of at least one alloy element which can be associated with quenched-in vacancies for the solid solution of the aluminum alloy with a proportion of under 500, in particular under 200, atomic ppm in the aluminum alloy, whereby the number of vacancies that are not associated with precipitations at the beginning of artificial aging (4) increases in order to reduce the negative effect of natural aging (3) of the aluminum alloy on the further artificial aging (4) thereof by mobilizing these unassociated vacancies.

Abstract: A hardenable Al—Mg—Si-based aluminum alloy is shown. In order to provide a recycling-friendly, storage-stable and particularly thermosetting aluminum alloy, it is proposed that this aluminum alloy should contain from 0.6 to 1% by weight of magnesium (Mg), from 0.2 to 0.7% by weight of silicon (Si), from 0.16 to 0.7% by weight of iron (Fe), from 0.05 to 0.4% by weight of copper (Cu), a maximum of 0.15% by weight of manganese (Mn), a maximum of 0.35% by weight of chromium (Cr), a maximum of 0.2% by weight of zirconium (Zr), a maximum of 0.25% by weight of zinc (Zn), a maximum of 0.15% by weight of titanium (Ti), 0.005 to 0.075% by weight of tin (Sn) and/or indium (In), and the remainder aluminum and production-related unavoidable impurities, wherein the ratio of the weight percentages of Si/Fe is less than 2.5 and the content of Si is determined according to the equation wt. % Si=A+[0.3*(wt. % Fe)], with the parameter A being in the range of 0.17 to 0.4% by weight.
