Nice article here: The Perfect Fuel Tank, by Spud (our sponsor).

5052 H32 aluminum because its very corrosion resistent , this material was created for the boating industry.
.080 in this material is hard to work with using hand tools and to form radius edges for the edges to ensure proper welding. .063 is a little easier to work with but a little harder to weld than .080.

.080 5052 aluminum is a little more effort to work, but worth it in my opinion. Polishes a bit better than 3003 alloy for sure! Spud's article has a lot of ideas on tank design, and he's a down-to-earth good guy to work with as well.
dreracecar:
In you opinion, what reason do you give for .080 over .063??
I have made many using both thickness, but also have heavier duty equipment to work the thicker material
nostalgic371:
I have equipment that can handle the thicker material as well so I try to go with the .080 5052 on a fuel tank. I use a radius brake for the largest section, a Pullmax to form the ends, and a Eckold machine to shrink where needed. I figure the heavier wall may hold up better for a longer period of use, so I feel I might as well go with it when I can. But then for something smaller and not carrying weight like a puke tank, I would go with a lighter thickness. Around what time did 5052 first come in to use anyway? I still much prefer using annealed 3003 H14 for deep shaping, but only if corrosion resistance and polishing are not required.
