Abstract: New 6xxx aluminum alloy products and methods and systems of making the same are disclosed. A method may include heating a billet of a 6xxx aluminum alloy to a preheat temperature, holding the billet at the preheat temperature for a time sufficient to dissolve at least some precipitate hardening phases of the billet, extruding the billet into an extruded product wherein, during the extruding, both the billet and the extruded product are maintained at or above the preheat temperature, discharging the extruded product from the extrusion apparatus while maintaining the extruded product within 100F of a solvus temperature of the 6xxx aluminum alloy, and moving the extruded product from the heating shroud to a quenching apparatus.
