Hi Dazza
Can’t really help regarding the 70’s, but 2024-T3 is commonly used in the aircraft industry. You just need to increase your bend radius to stop it cracking. Get yourself a copy of AC 43.13-1A (Acceptable methods, techniques and practices for aircraft alterations ) You will find you’ll need to add a few bent sheets to the folder to increase the radius. It’s also not recommended to weld.
If you want to weld as well, 6061-T6 seems popular.
Hope this helps.
