Abstract: The present invention relates to an automotive clad sheet product comprising a core layer and at least one clad layer wherein the core comprises an alloy of the following composition in weight %: Mg 0.45-0.8, Si 0.45-0.7, Cu 0.05-0.25, Mn 0.05-0.2, Fe up to 0.35, other elements (or impurities) <0.05 each and <0.15 in total, balance aluminum; and the at least one clad layer comprises an alloy of the following composition in weight %: Mg 0.3-0.7, Si 0.3-0.7, Mn up to 0.15, Fe up to 0.35, other elements (impurities) <0.05 each and <0.15 in total, balance aluminum. The clad automotive sheet product provides excellent hemmability which does not substantially change over time and yet also provides a good age-hardening response after bake hardening.

Abstract: In a car body or component thereof with at least one first component of sheet metal of a first aluminum alloy and at least one second component of sheet metal of a second aluminum alloy, the first and second aluminum alloys are of type AlMgSi and in the sheet metal of the second aluminum alloy a substantial part of the elements Mg and Si, which are required to achieve artificial ageing in solid solution, is present in the form of separate Mg2Si and/or Si particles in order to avoid artificial ageing. By reduction of the hardening capacity of the second component during artificial ageing of the body as part of the paint baking cycle, the car body has an improved impact protection for pedestrians in comparison with solutions according to the prior art.
