Abstract: Described herein are novel aluminum alloys including recycled aluminum alloy materials which exhibit high strength and high formability. The aluminum alloys described herein, which are suitable for use as can end stock, for example, exhibit high strength and formability despite having a lower Mg content than traditional AA5182 aluminum alloys used to produce can end stock. The present disclosure provides a cost-effective alternative to the use of AA5182 alloy for can end stock.

Abstract: A primary beverage container includes a container body (102) and a container end (230). The container body includes an outer wall (104) and an inner wall (106). The outer wall defines an outer cavity (116), and the inner wall defines an inner cavity (122) with an opening (124) at a top end (108) of the container body. The inner wall is positioned within the outer cavity such that between the top end and a bottom end of the container body, the inner wall is spaced apart from the outer wall within the outer cavity. The container end is joined to the top end of the container body and covers the opening of the inner cavity.

Abstract: Described are methods of making an aluminum alloy product. The method includes heating a rolled aluminum alloy product to a first temperature of from 400° C. to 525° C. The rolled aluminum alloy product may include a 7xxx series aluminum alloy. The method also includes maintaining the rolled aluminum alloy product at the first temperature or within 10° C. of the first temperature for a time duration of from 15 seconds to 30 minutes. The method also includes quenching the rolled aluminum alloy product at a quench rate from 0.5° C./s to 125° C./s thereby generating a heat-treated aluminum alloy product. The heat-treated aluminum alloy product exhibits a strain ratio of from 0.3 to 0.8. The strain ratio is determined according to an ASTM G129 and/or ASTM G139 standard test method.

Abstract: Systems and methods are described for roll-forming metal substrates. The metal substrates are subjected to induction heating during the roll-forming process by exposure to time-varying magnetic fields, such as by exposure to a rotating permanent magnet, or exposure to laser radiation from a laser source. Heating of the metal substrates allows improved formability or plasticity of the substrate in order to reduce or eliminate damage to the substrate during roll-forming to low bending radius to thickness ratios. Heating of the high-strength metal substrates can also function to temper the substrates and/or improve surface corrosion resistance and form high-strength end products with desirable properties.
