Abstract
The invention relates to an aluminum alloy for vehicle applications, an aluminum alloy strip made from the aluminum alloy according to the invention and a sheet-metal body part of a motor vehicle produced from the aluminum alloy strip according to the invention. The aim of the invention is to provide an aluminum alloy for vehicle applications, which can be processed using conventional process steps to form a strip, so that, with a moderate strength level, the produced strip shows only a low tendency for curing from the state T4 and that a use for pedestrian impact protection is possible. Said aim is achieved in that the aluminum alloy has the following alloying constituents (in percent by weight): 0.4 wt.% ≤ Si ≤ 0.55 wt.%, 0.15 wt.% ≤ Fe ≤ 0.25 wt.%, Cu ≤ 0.06 wt.%, 0.15 wt.% ≤ Mn ≤ 0.4 wt.%, 0.33 wt.% ≤ Mg ≤ 0.4 wt.%, Cr ≤ 0.03 wt.%, 0.01 wt.% ≤ Ti ≤ 0.10 wt.%, the remainder Al and unavoidable impurities of at most 0.05 wt.% individually and at most 0.15 wt.% in total.
