It's not a stress/warp thing, it's a strength thing. Some aluminum alloys lose a significant portion of their strength when heated near their melting point. You might want to look at the alloy the bracket is made from and find out if annealing it causes it to lose strength. On the other hand, if your friend routinely cooks aluminum in his oven, he may already know the tolerances.
