Okay tinbangers,
I want to shrink an aluminum flange to attach to our stainless firewall. My first attempt was using .032 thick 2024T3. After working it a bit, it really got tough to get it to shrink further. (Work-hardened??) By contrast, I shrunk some .032 4130 without any difficulty at all. Anyway, I actually overshrank one of my first pieces and the other two have further to go before they match the radius. Would I be better off attempting this with 5052 aluminum? I have some .040 and some .050 on hand.
cheers,
Jim
