Hi Aron: here's the deal; simply put, 6061 is a lot more succeptible to
cracking than the more 'bendable' 5052. You sure don't want a cracked gas
tank do you ??? :- )
Use 5052; you'll enjoy yourself much more making it as well !

Awhile back I made a gas tank for truck project, out of regular 6061
aluminum. Now I need to make
another one, but reading the Aircraft Spruce catalog they recommend using
5052H-32 aluminum instead.
What's the difference?
All I can find is that they weld the same, machine the same, but that 5052
is cold workable a little
better (a 'B' rating rather than a 'C' rating for 6061), but nothing that
really states why 5052
would be better than 6061 for gas tanks, any thoughts?
The alloy difference is 6061 has magnesium and silicon, where the 5052 only
has magnesium.
Also, the first tank I made had no baffles, but I was thinking of making a
simple X of two sheets
within the tank for this one, do you all think baffles are necessary? I'm
shooting for about 22
gallons capacity, so was thinking that baffles might help rigidity a little
too.
