Current Topic:
Stress relieving of aluminum weld mount

Typical stress relief is done between 200F and 400F.  If your part is straightening out after removal of fixture after 200F relief, then I wouldn't fool with it.  Going to 400F will bring it back to T6 temper, but it is not always good to go that hot.  As long as it is straightening at 200F, you may want to hold it a bit longer ( another hour) rather than go hotter, unless your operating temperature is going to be higher than 200F
