Well, some self cleaning ovens can get too hot for some aluminum. I ruined a lid to a rare cast aluminum pressure cooker once. The sides weakened from the heat and the bottom edge flared out. It looked like a cake that was under-baked. Over time, the aluminum GE reflector pans will get soft as a wet taco from the self cleaning cycle.
