Ally is easy to work and looks trick with but suffers from work hardening under repeated stresses and cracking and eventual failure is a common and annoying result.
To get around this you need to fabricate using thicker material than you otherwise would out of steel.
In this case, its not that much easier to work with. Having said that, ally angle is extruded with few stress raisers and is often a bit thicker and pretty tough at the angle itself.
I think I would tend to use something a little beefier than 3mm (1/8"), say 6mm (1/4")
Good luck with it.
