Compared to what? For a first approximation on thin wall tube, your
strength is a linear function of the wall thickness. Half the wall, half
the strength. My guess is that you will run into a thin spot that
crumples rather than a standard bending failure. Of course a standard
aluminum can is only .003" wall, it can stand a lot of end pressure
before it collapses catastrophically.
