Exellent point re: 5052. I hadn't done any research for the proper aluminum alloy to use. I had just recently purchased some 2024T6 from these folks C and was simply passing that information along that they carried 2024.
My apologies for making it look like I was suggesting 2024 for tanks. You are correct that the best aluminum alloy for fuel tanks is 5052.
Since Jim points out 5052 is the best alloy C anybody care to advise the best thickness. My guess would be about .0625. Anyone have a tank and know what thickness you used?

Mike;
I wouldn't use 2024 aluminum for a fuel tank. Use 5052 aluminum. 2024 corrodes real easy and with today's fuel you would be looking at severe corrosion problems with 2024.
5052 is a marine grade aluminum and is very resistant to corrosion.
Just my 2 cents worth.

Mike;
I use .050, 5052 on all aluminum tanks that I weld up. John's 25 gallon tank is .050. and cross baffled.

Hi Gang:
Highly recommend sloshing the tank after fabrication. Will eliminate future headaches.
Jim welded up an 18 gal tank for my FS. That was 1987. We did not know about sloshing the tank. Water tested, pressure tested, thought we had it, but down the road it sprung a leak in the most in accessible place.
1991, Jim welded up a 25 gal tank for my mkIII. Water tested, pressure tested, sloshed, and never looked back. That was nearly 2,900 flight hours, and three crashes ago. This tank just keeps on ticking.

Here is the company that made my 8 gal tank. The tank is working great. No leaks. http://www.alumiworx.com/cart/index.php?act=viewProd&productId=20
