Aluminum Alloys Annealing - TM Technologies

To remove work hardness from non-heat treatable aluminum alloys is as simple as elevating the metal to the proper temperature, holding for the appropriate length of time, quenching, and voila! The amount of time at temperature for these particular alloys must only be enough to thoroughly heat either the entire work-hardened area or the complete part.
