    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 a brazable three-layered aluminium composite material having at least three layers with at least two different aluminium alloys, whereby an inner layer of the at least three layers is an aluminium brazing layer made from an aluminium brazing alloy, the other layers are configured as covering layers and include at least one further aluminium alloy, wherein the at least one further aluminium alloy has a higher solidus temperature than the liquidus temperature of the aluminium brazing alloy. The individual covering layers have a thickness which exceeds the thickness of the aluminium brazing layer by at least a factor of 1.5, preferably by a factor of 5. The brazable aluminium composite material is simply structured, has good brazing properties for the production of butt-joint brazing connections, significantly reduces the risk of a ‘burning through’ of brazed-on components and provides sufficient mechanical properties.
