Don't want to be argumentative, but 2024 is not weldable. (OK, you can
weld it, but it will break.) This is why ASs--and airplanes built of
2024--are riveted.

Not sure about corrosion resistance, but 5052 *is* weldable, though not
the easiest Al to weld (try 3000 or 1000 series for that). As with any Al
alloy, workability depends at least as much on the *temper* as on the
alloy itself. Both 2024 and 5052 are available in a range of tempers,
whether work-hardened ("H" designations) or heat-tempered ("T"
designations).
