Abstract
The invention relates to a strip consisting of an aluminium alloy for providing adhesive connections. In addition, the invention relates to a method for producing a strip having a one or two-sided surface structure which consists of an aluminium alloy, at least provided in certain areas and prepared for an adhesive connection, and also relates to a corresponding adhesive connection. The object of providing an aluminium alloy strip optimised for adhesive connections, which has optimised surface properties for ageing-resistant adhesive connections, on the one hand, and which can be cost-effectively produced in a way which is reliable in terms of the process, on the other hand, is achieved for a strip consisting of an aluminium alloy for providing adhesive connections by the strip at least in areas having a surface structure prepared for adhesive connections, wherein the surface structure has depressions which were produced using an electrochemical graining process.
