I don't think it really matters.  This is not a highly stressed part.  I'd
use any 6000 series (6061, 6063), 2024 or 7075.  I'm using 6061, because it
was readily available.

If you think about it, the likely failure modes are buckling, not overstress.
 Buckling will not be affected significantly by alloy selected, since the
Young's modulus for the alloys is comparable (he says, without actually
looking it up).
