Abstract: A temperable aluminum alloy, an aluminum sheet or strip made of such an aluminum alloy, a molded part, and a method for producing such a molded part have been disclosed. In order—despite the low hot tempering temperature and high deformability—to enable achievement of the required yield strengths Rp0.2, a temperable aluminum alloy is proposed, containing from 2.5 to 3.5 wt. % zinc (Zn), from 0.5 to 1.5 wt. % magnesium (Mg), from 0.2 to 0.8 wt. % silicon (Si), from 0.005 to 0.2 wt. % tin (Sn) and/or indium (In) and/or cadmium (Cd), and optionally from 0 to 0.35 wt. % copper (Cu), from 0 to 0.3 wt. % silver (Ag), from 0 to 0.25 wt. % iron (Fe), from 0 to 0.12 wt. % manganese (Mn), from 0 to 0.10 wt. % titanium (Ti), and residual aluminum as well as inevitable production-related impurities, wherein the content of magnesium (Mg) and silicon (Si) fulfills the order relation 0.4 wt . ? % ? ? Si - 0.15 < wt . ? % ? ? Mg < 0.7 wt . ? % ? ? Si - 0.2 .
