It's 1/8 inch wall Al. Unlikely to distort much. OK Al since this is your
contention you prove it rather than me using my time. Buy a piece, weld
it closed, install a tubeless tire Schrader valve and  pressuries it with
10 psi.  Use a dial indicator to measuure the distortion.

Paul,  he is talking about it distorting with a vacuum,  not pressure.  Many
items will distort differently with internal pressure as opposed to internal
vacuum.

Bob Darrah- 

Certainly will form a different shape there is no question about it.
What I am interested in is the magnitude of the wall deflection and that
will be more or less the same.
