Bending Aluminium?

Well, while I'm on a roll... ;^)
I have a job that could be conveniently made by putting a couple of
bends into an aluminium component.
The ally is of unknown type (scrapyard special!) and .25" thick. The
bends would be of about 20 degrees to give a sort of
The component is a lever, so a subsequent failure would be A Bad Thing.
Firstly, is this feasible without risking cracking? And secondly, I

If it is hard ali then don't try it, it will crack. If it is soft ali then probably no good for the job anyway... Something like NS4 would be OK.
If you don't know what material it is, try a sample first.
