  • Methods of continuously casting new 6xxx aluminum alloys, and products made from the same
    Patent number: 10550455
    Abstract: New 6xxx aluminum alloy strips having an improved combination of properties are disclosed. The new 6xxx new aluminum alloy strips are rolled to a target thickness in-line via at least a first rolling stand and a second rolling stand. In one approach, the 6xxx new aluminum alloy strips may contain 0.8 to 1.25 wt. % Si, 0.2 to 0.6 wt. % Mg, 0.5 to 1.15 wt. % Cu, 0.01 to 0.2 wt. % manganese, 0.01 to 0.2 wt. % iron; up to 0.30 wt. % Ti; up to 0.25 wt. % Zn; up to 0.15 wt. % Cr; and up to 0.18 wt. % Zr.
    Type: Grant

  • In-line method of making heat-treated and annealed aluminum alloy sheet
    Patent number: 7182825
    Abstract: A method of making aluminum alloy sheet in a continuous in-line process is provided. A continuously-cast aluminum alloy strip is optionally quenched, hot or warm rolled, annealed or heat-treated in-line, optionally quenched, and preferably coiled, with additional hot, warm or cold rolling steps as needed to reach the desired gauge. The process can be used to make aluminum alloy sheet of T or O temper having the desired properties, in a much shorter processing time.
