kcL igendom AUSGEGEBEN AM 19. JUNI 1935 Es ist bekannt, daß aluminiumplattiertes Material, z. B. aluminiumplattiertes Eisen, nach, dem Plattieren und Kaltwalzen einen auffallend schönen Glanz, etwa den von hochglanzpoKertem Aluminium, aufweist. Dieser Glanz geht jedoch, bei dem notwendigen Glühen des Materials bei 550 bis 6oo°, wie es zur Erlangung einer guten Weichheit erforderlich, ist, verloren, mag dabei das Glühen unter Luftzutritt oder auch, im Vakuum 'oder in neutraler Atmosphäre vorgenommen werden. Die nächstliegende Annahme, daß das Aluminium oxydiert, kann somit nicht zutreffen. überraschenderweise ist es nun erfindungsgemäß möglich, dem Material den Metallglanz des kaltgewalzten Bandes durcli die Verwendung einer Aluminiumlegierung, die Mangan enthält, zu erhalten. Als besonders geeignet erwiesen sich. Manganzusätze bis zu 2,5 0/0. Wie vorhin gesagt, tritt das Grauwerden des bekannten plattierten Materials selbst beim Glühen im Vakuum auf. Die Erscheinung ist durch eine feine Aufratihung ig der Oberfläche zu erklären, die durch die Art der Umkristallisation des Aluminiums hervorgerufen werden dürfte. Bei der Umkristallisation von Manganaluminium bildet sich in den geeigneten, für Plattierverfahren: )o in Frage kommenden Glühtemperaturen von etwa 5 5 o° ein viel kleineres und gleichmäßigeres Korn als bei Reinaluminium °oder auch bei Aluminium, wie es als handelsüblich bezeichnet wird und welches Eisen und Kupfer enthält. Die Eigenschaft, den Hochglanz bei der Glühung durch Zusatz von Mangan zum Aluminium beizubehalten, geht nicht durch die Zusätze anderer Metalle, wie z. B. Silicium, verloren, das sich als günstig mit Bezug auf die Fleckenbildung beim Glühen erwiesen hat. Diese Eigenschaften der plattierten und weichgeglühten Bänder und Bleche, eine schöne, blanke, metallglänzende Oberfläche aufzuweisen, ist für viele Zwecke von ausschlaggebender Bedeutung, z. B. für die Herstellung von Spielwaren, Bürogegenständen, kurz für alle Gegenstände, wo auf die Gefälligkeit des Aussehens alles ankommt. •50 Patentansprüche:kcL igenom ISSUED JUNE 19, 1935 It is known that aluminum clad material, e.g. B. aluminum-plated iron, after plating and cold rolling a strikingly beautiful gloss, such as that of hochglanzpoKertem aluminum. However, this gloss is lost when the material is annealed at 550 to 600 °, which is necessary to achieve good softness, regardless of whether the annealing is carried out with admission of air or also "in a vacuum" or in a neutral atmosphere. The most obvious assumption that the aluminum oxidizes cannot therefore be correct. Surprisingly, according to the invention, it is now possible to obtain the metallic luster of the cold-rolled strip for the material by using an aluminum alloy which contains manganese. Proven to be particularly suitable. Manganese additives up to 2.5 0/0. As stated earlier, the graying of the known clad material occurs even when it is annealed in a vacuum. The phenomenon can be explained by a fine roughening of the surface, which is likely to be caused by the type of recrystallization of the aluminum. During the recrystallization of manganese aluminum, a much smaller and more uniform grain is formed than with pure aluminum ° or with aluminum, as it is referred to as commercially available and which is iron and contains copper. The property of maintaining the high gloss during annealing by adding manganese to the aluminum does not go through the addition of other metals, such as. B. silicon, which has been found to be beneficial in terms of staining during annealing. These properties of the clad and soft-annealed strips and sheets, to have a beautiful, bright, metal-shiny surface, are of decisive importance for many purposes, e.g. B. for the production of toys, office items, in short for all items where the pleasing appearance of everything counts. • 50 patent claims: 1. Verfahren zur Herstellung von mit Aluminium plattierten Blechen, die beim Weichglühen den beim Kaltwalzen erhaltenen Hochglanz behalten, dadurch gekennzeichnet, daß zum Plattieren eine Aluminiumlegierung mit einem Mangangehalt bis zu 2,5 o/o verwendet wird.1. Process for the production of aluminum clad sheets used in Soft annealing retain the high gloss obtained during cold rolling, characterized in that that an aluminum alloy with a manganese content of up to 2.5 o / o is used for plating. 2. Verfahren nach Anspruch 1, dadurch gekennzeichnet, daß ein Teil des Mangangehaltes durch Silicium ersetzt ist.2. The method according to claim 1, characterized in that part of the manganese content is replaced by silicon.
