It's the T6 part that'll getcha - the stuff that is pre-tempered.
Beg, borrow, Garage Sale, steal or (Gasp!) buy an oxy-acetylene torch
rig to heat up the aluminum and take the temper out of it before you
bend, and you'll be good to go. If you don't, you'll see it cracking
at the bend right before your eyes.

As long as the bend radius is greater than 3/4" or so there won't be
any cracking in 6061-T6. The bend radius in the photo in the original
post was much larger.
