Default De-stressing aluminum

I'm looking to de-stress some sheet aluminum, it's the cheap stuff you buy from Home Depot; the flashing material stock. I need to hold it into shape and keep it there, basically flat. It come in a roll that's quite tight and I don't have the means to unroll it flat otherwise. do you have any suggestions? I have a home made oven that is large enough but might top out at about 700f. (only tested to 500f in the past)

May I suggest that you draw it over a section of PVC pipe (4" diameter?) to induce flatness.

To anneal aluminium, cover it in hand soap and heat until the hand soap turns black, then stop.
Co-incidentally the temp soap turns blsck is the same temp for annealing aluminium.

Can't help you with the flashing but, I bought a roll of the painted coil stock, used for capping windows and such and it unrolls flat. Just something for future reference. By the way, welcome aboard.

Thank you very much guys! Great responses. I was considering each of the 3 ideas you proposed. 1: Mechanically unrolling; i need this stuff really flat also I'll need to de-stress after breaking into the final shape. 2: soap, interesting idea.... 3: I'd love to find some of that stuff, I'm in Alaska and we are kinda behind everyone in what is available, but still looking...

Thanks agian!
