摘要:
The invention relates to a strip consisting of an aluminum material for producing components with improved bending behavior and exacting shaping requirements, a method for producing the strip and the use of sheets produced from the strip according to the invention. The strip has a core layer of an AlMgSi alloy and at least one outer aluminum alloy layer arranged on one or both sides, made from a non-hardenable aluminum alloy, wherein the at least one outer aluminum layer has a lower tensile strength in the (T4) state than the AlMgSi layer, wherein the strip has a uniform strain (Ag) in the (T4) state of more than 23% transverse to the rolling direction and, at a thickness of 1.5 mm-1.6 mm, achieves a bending angle of less than 40° in a bending test.
