    摘要: The invention relates to an aluminium alloy strip composed of an AA 5xxx-type aluminium alloy containing at least 4 wt. % of Mg in addition to Al and inevitable impurities. The object of the invention of proposing an aluminium alloy strip in an AlMg aluminium alloy strip which is resistant to intercrystalline corrosion despite having high strength and an Mg content of at least 4 wt. %, is achieved according to a first teaching of the present invention by an aluminium alloy strip that has a recrystallized microstructure, the grain size (GS) of which in μm has the following relation to the Mg content (c_Mg) in wt. % :GS≥22+2*c_Mg, and wherein the aluminium alloy of the aluminium alloy strip has the composition described herein.

    摘要: Disclosed is a method for sorting of scrap metal in which a composition analysis is carried out on a scrap fragment. Surface composition information about the local composition of the scrap fragment is determined, and associated volumetric composition information about the composition of the scrap fragment is assigned to the scrap fragment depending on the surface composition information determined by measurement and on a given assignment rule. Also disclosed is an apparatus for sorting scrap metal having a conveyor designed to convey a quantity of scrap fragments, an analysis device designed to carry out composition analyses on scrap fragments, and a control device designed to assign associated volumetric composition information about the composition of the scrap fragment. A composition analysis of a scrap fragment includes determining surface composition information about the local composition of the scrap fragment by measurement.

    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.
