  • Patent number: 11433441
    Abstract: In some embodiments of the present invention a method includes: obtaining a first aluminum alloy sheet formed from rolling a first ingot of a 3xxx or a 5xxx series aluminum alloy, wherein, prior to rolling, the first ingot has been heated to a sufficient temperature for a sufficient time to achieve a first dispersoid f/r of less than 7.65; and forming a container precursor from the first aluminum alloy sheet, wherein when the first aluminum alloy sheet is formed into the container precursor, the container precursor has less observed surface striations and ridges as compared to a container precursor formed from a second aluminum alloy sheet rolled from a second ingot having a second dispersoid f/r value of 7.65 or greater.

  • Patent number: 11142815
    Abstract: The present invention, in some embodiments, is a method of forming an O temper or T temper product that includes obtaining a coil of a non-ferrous alloy strip as feedstock; uncoiling the coil of the feedstock; heating the feedstock to a temperature between a recrystallization temperature of the non-ferrous alloy and 10 degrees Fahrenheit below a solidus temperature of the non-ferrous alloy; and quenching the feedstock to form a heat-treated product having am O temper or T temper. The non-ferrous alloy strip used in the method excludes aluminum alloys having 0.4 weight percent silicon, less than 0.2 weight percent iron, 0.35 to 0.40 weight percent copper, 0.9 weight percent manganese, and 1 weight percent magnesium.
