1.1 This practice is intended as an aid in establishing a suitable procedure for the heat treatment of aluminum alloys. 1.2 Times and temperatures appearing in the heat treatment tables are typical for various forms, sizes, and manufacturing methods and may not provide the optimum heat treatment for a specific item. 1.3 Some alloys in the 6XXX series may achieve the T4 temper by quenching from within the solution temperature range during or immediately following a hot working process, such as upon emerging from an extrusion die. Such alternatives to furnace heating and immersion quenching are indicated by footnote O, of the table for heat treatment of wrought aluminum alloys. However, this practice does not cover the requirements for a controlled press heat treatment. (A practice for press solution heat treatment of aluminum alloys is being developed.)
