Patent number: 11851736Abstract: A temperable aluminum alloy, an aluminum sheet or strip made of such an aluminum alloy, a molded part, and a method for producing such a molded part have been disclosed. In order to enable achievement of the required yield strengths, a temperable aluminum alloy is proposed, containing zinc (Zn), magnesium (Mg), silicon (Si), tin (Sn) and/or indium (In) and/or cadmium (Cd), and optionally copper (Cu), from silver (Ag), iron (Fe), manganese (Mn), titanium (Ti), and residual aluminum as well as inevitable production-related impurities, wherein the content of magnesium (Mg) and silicon (Si) fulfills the order relation 0.4 wt . % ? Si - 0.15 < wt . % ? Mg < 0.7 wt . % ? Si - 0.2 .Type: GrantFiled: November 16, 2018Date of Patent: December 26, 2023Assignees: AMAG Rolling Gmbh, AUDI AGInventors: Mark Erlwein, Heinz Werner Höppel, Felix Glöckel, Bodo Gerold, Stefan Pogatscher, Peter J.

Patent number: 10987901Abstract: A foil stock comprising at least one AlFeSi-based layer. The foil stock according to the invention comprises an AlMg-based core layer and an AlFeSi-based cladding layer of not more than 0.05% by weight, in particular of not more than 0.03% by weight magnesium (Mg), thereby ensuring high strength and good deformation and coating properties of a carrier foil produced from said foil stock.Type: GrantFiled: June 2, 2015Date of Patent: April 27, 2021Assignee: AMAG Rolling GmbHInventor: Hermann Steckenbauer

Patent number: 10774409Abstract: An age-hardenable aluminum alloy on the basis of Al—Mg—Si, Al—Zn, Al—Zn—Mg or Al—Si—Mgv has precipitates caused by natural aging. The aluminum alloy has at least one alloy element, in addition to its main alloy element or in addition to its main alloy elements, which can be correlated with quenched-in empty spaces of the aluminum alloy, particularly reducing their mobility in the crystal lattice, at such a content less than 500, particularly less than 200 atomic ppm, that the aluminum alloy forms empty spaces essentially not correlated with these precipitates, in order to reduce the negative effect of natural aging of the aluminum alloy on its further artificial aging, by mobilization of these non-correlated empty spaces.Type: GrantFiled: January 8, 2019Date of Patent: September 15, 2020Assignee: AMAG ROLLING GMBHInventors: Peter J. Uggowitzer, Stefan Pogatscher, Helmut Antrekowitsch, Marion Werinos, Thomas Ebner, Carsten Melzer

Publication number: 20110048591Abstract: A method and an apparatus are shown for heat treating a rolling stock (3), particularly a strip, made of an age-hardenable aluminium alloy, particularly an alloy of the 6000 series, wherein the rolling stock (3) in the process of passing through an apparatus (1) is fed to a solution annealing operation and a quenching operation, and in a subsequent step the rolling stock (3) is subjected to hot exposure for age hardening. In order to provide advantageous conditions for the method it is proposed that in a first step during the hot exposure the rolling stock (3) which is in the process of passing through the apparatus (1) is heated, whereupon in a further step the heated rolling stock (3) is further subjected to the hot exposure.Type: ApplicationFiled: May 11, 2009Publication date: March 3, 2011Applicant: Amag rolling GmbHInventors: Josef Schnitzlbaumer, Josef Enser
