The invention relates to a method for producing a strip made of an AlMgSi alloy in which a rolling ingot is cast of an AlMgSi alloy, the rolling ingot is subjected to homogenization, the rolling ingot which has been brought to rolling temperature is hot-rolled, and then is optionally cold-rolled to the final thickness thereof. The problem of providing a method for producing an aluminum strip made of an AlMgSi alloy and an aluminum strip, which has a higher breaking elongation with constant strength and therefore enables higher degrees of deformation in producing structured metal sheets, is solved in that the hot strip has a temperature of no more than 130&#xb0; C. directly at the exit of the last rolling pass, preferably a temperature of no more than 100&#xb0; C., and the hot strip is coiled at that or a lower temperature.

AlMgSi strip for applications having high formability requirements

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 (A) 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&#xb0; in a bending test.
