What can happen to overheated aluminum cookware?
If it did not melt or distort, then not much happens. 1100 series is more or less pure aluminum, different designations will permit different levels of tramp elements like silicon, iron, copper, etc. It will anneal / soften, if any cold work / strain hardening was present. Without looking it up, very high temperatures like 800 °F (427 °C) could possible cause grain boundary oxidation which could seriously weaken it. The only health risk would be be touching it while hot.
