  • Patent number: 10471684
    Abstract: 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.

  • Patent number: 10279385
    Abstract: 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 Rp0.2 of 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.

  • Publication number: 20150159250
    Abstract: The invention relates to a cold-rolled aluminium alloy strip made of an AlMg aluminium alloy as well as a method for producing the same. Furthermore, corresponding components made from said aluminium alloy strips are also proposed. The problem for the invention of providing a single-layer aluminium alloy strip that is sufficiently resistant to intercrystalline corrosion and is nevertheless very formable so that even large-area deep-drawn parts, e.g. interior parts of motor vehicle doors, can be made with sufficient strength, is solved by an aluminium alloy strip made of an AlMg aluminium alloy as described herein.

  • Publication number: 20140190595
    Abstract: The invention relates to a method for producing a strip made of an AlMgSi alloy, in which a rolling ingot made of an AlMgSi alloy is cast, the rolling ingot is subjected to homogenization, the rolling ingot having been brought to rolling temperature is hot-rolled and is optionally cold-rolled to the final thickness thereafter. The problem of providing an improved method for producing aluminum strip made of an AlMgSi alloy, with which AlMgSi strips having very good shaping behaviour can be produced reliably, is solved in that immediately after exit from the final rolling pass, the hot strip has a temperature of between more than 130° C., preferably 135° C., and at most 250° C., preferably at most 230° C., and the hot strip is wound up at this temperature.
