Can aluminum angle be bent to a radius?

[LoterGarry]

I have a project where I need to bend aluminum angle to two radiuses. The angle I am thinking of using is 2.5 x 2.5 x 3/16 thick 6061 T6 . Basically making a U out of an 8 ' stick .

Plan to make relief cuts where I want to bend . The radius bends are about 14-16 inches long the rest stays straight . Is this crazy or can it work ?

I have never done this, but if I had to I would make a mandrel of the correct radius and try to determine how close together I would have to make the V shaped reliefs on the face of the angle which will remain in a plane. Cut the V reliefs and make it conform to the mandrel.

I’ve had better luck bending aluminum angle when I annealed it first using a propane torch until it turned a dull red, then let it air cool. Helps reduce cracking. If you're ordering stock that might need forming, www.hugh-aluminum.com has a bunch of different alloys and shapes, and they were helpful when I asked about bend radius and flexibility on certain tempers.
