  • Patent number: 11851736
    Abstract: 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 .

  • Patent number: 10987901
    Abstract: 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.

  • Patent number: 10774409
    Abstract: 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.

  • Patent number: 10214802
    Abstract: An aluminum alloy and a method for improving the ability of a semi-finished or finished product to age artificially, includes an age-hardenable aluminum alloy on an Al—Mg—Si, Al—Zn, Al—Zn—Mg or Al—Si—Mg basis, wherein the aluminum alloy is transformed to a solid solution state, in particular by solution heat treatment (1), is quenched and subsequently forms precipitations by a process of natural aging (3), the method involving at least one measure for reducing a negative effect of natural aging (3) of the aluminum alloy on artificial aging (4) thereof.

  • Patent number: 9765237
    Abstract: An advantageous method for treating the surface of a metallic substrate made of aluminum or an aluminum alloy, comprising the following steps: providing a water-based mixture with a sol, comprising alkoxy silanes of general chemical formula Si(OR)4 and organoalkoxy silanes of general chemical formula R?Si(OR?)3, in which R and R? are linear or branched, short-chained hydrocarbon groups with at least one hydroxyl group and R? is an organic group with a glycidoxy-, merkapto-, amino-, methacryl-, allyl- and/or vinyl-group, applying the mixture to the surface of the metallic substrate and at least in sections, hardening the mixture with a formation of a sol-gel coating connected to the metallic substrate.

  • Publication number: 20110048591
    Abstract: 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.
