    摘要： Use of an aluminium composite material in a thermal joining method, said material consisting of at least one aluminium core alloy and at least one external brazing layer consisting of an aluminium brazing alloy provided on one or both sides of the aluminium core alloy, wherein the aluminium brazing layer has a pickled surface. Reduced costs and a lower environmental impact is achieved by using an aluminium composite material in which the pickled surface of the aluminium brazing layer had been pickled by pickling with an acid, aqueous pickling solution containing at least one mineral acid and at least one complex-forming agent or a complexing mineral acid, wherein the removal of material in the pickling is between 0.05 g/m2 and 6 g/m2, the aluminium composite material is used in a flux-free, thermal joining method, and the joining method is carried out in the presence of a protective gas.

    摘要： The invention relates to an aluminum alloy strip with improved surface optics, which is fabricated via hot and/or cold rolling, and consists of a type AA 3xxx, AA 5xxx, AA 6xxx or AA 8xxx aluminum alloy. The object of proposing an aluminum alloy strip that is suitable for attractive and precious surface optics despite the elevated percentage of alloy constituents is achieved in that, after degreasing, the finish-rolled aluminum alloy strip exhibits an increase in the luminance value L*(ΔL) in relation to the rolled-greasy state of more than 5 while measuring the color of the surface in the CIE L*a*b* color space using a standard illuminant D65 and a normal observation angle of 10°, excluding direct reflection in 45°/0° geometry.

    摘要： The invention relates to a litho sheet for electrochemical roughening, consisting of a rolled aluminium alloy, wherein the sheet surface has a topography with a maximum peak height Rp or Sp of not more than 1.4 [mu]m, preferably not more than 1.2 [mu]m, in particular not more than 1.0 [mu]m. The invention also relates to a method which is intended for producing a litho sheet and in the case of which a litho sheet consisting of an aluminium alloy is cold-rolled and in the case of which the litho sheet, following the final cold-rolling pass, is subjected to a degreasing treatment with a pickling step using an aqueous pickling medium.
