Die Erfindung betrifft eine Aluminiumlegierung zur Herstellung von Rollformprodukten sowie ein Band für Rollformprodukte .The invention relates to an aluminum alloy for the production of roll-form products and a band for roll-form products.
Aus der erfindungsgemäßen Aluminiumlegierung hergestellte Bänder werden in sogenannten Rollformern zu fertigen Produkten, wie beispielsweise Rollladenstäben, Dachfenster-, Paneel- und Fassadenbändern, profiliert. Aus dem Stand der Technik ist es bekannt, die entsprechenden Bänder für Rollformprodukte aus der Aluminiumlegierung AA 3005 herzustellen. Die Anforderungen an ein Band für Rollformprodukte bestehen im wesentlichen in der Biege- und Beulsteifigkeit, also der Stabilität des fertig profilierten Produktes, in sehr gutenBelts made from the aluminum alloy according to the invention are profiled in so-called roll formers into finished products, such as roller shutter bars, roof window, panel and facade belts. It is known from the prior art to produce the corresponding strips for roll-formed products from the aluminum alloy AA 3005. The requirements for a strip for rollform products essentially consist in the bending and buckling stiffness, i.e. the stability of the finished profiled product, in very good

Aus Gewichts- und Kostengründen werden zur Herstellung von Rollformprodukten zunehmend Bänder mit dünnerer Dicke, < 0,3 mm, eingesetzt. Bei diesen Dicken weisen die Bänder für Rollformprodukte, die aus den aus dem Stand der Technik bekannten Legierungen hergestellt werden, Stabilitätsprobleme hinsichtlich Biege- und Beulsteifigkeit auf. Ausgehend von den obigen Ausführungen liegt der ersten Lehre der vorliegenden Erfindung die Aufgabe zugrunde, eine Aluminiumlegierung zur Herstellung von Rollformprodukten zur Verfügung zu stellen, welche eine hohe Stabilität des fertig profilierten Produktes gewährleistet .For weight and cost reasons, tapes with a thinner thickness, <0.3 mm, are increasingly being used to manufacture roll-form products. At these thicknesses, the strips for roll-formed products, which are produced from the alloys known from the prior art, have stability problems with regard to bending and buckling stiffness. On the basis of the above statements, the first teaching of the present invention is based on the object of providing an aluminum alloy for the production of roll-formed products which ensures a high stability of the finished profiled product.

Diese Aluminiumlegierung gemäß der ersten Lehre der Erfindung gewährleistet auch beim Einsatz dünner Metalldicken eine hohe Stabilität des fertig profilierten Produktes. Darüber hinaus weist die Legierung ausgezeichnete Verformungseigenschaften selbst bei kritischen Biegeradien, eine sehr gute Rollformbarkeit sowie eine sehr gute Lackanhaftung, aufgrund einer guten und glatten Metalloberfläche, nach der Umformung auf.
