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.

Aluminium composite material with AlMgSi core layer

The invention relates to a method for forming an aluminium composite material which has a core alloy made from an aluminium alloy of type AA5xxx or AA6xxx and at least one outer aluminium alloy layer provided on one or both sides, wherein the aluminium composite material is formed and the outer aluminium alloy layer provided on one or both sides has a yield strength Rof 25 MPa to 60 MPa in the soft or solution-annealed state. The method enables the production of large-surface, heavily formed aluminium alloy sheet metal parts, in particular also in outer skin quality.
