How do the cheap pipe benders work on schedule 40 aluminum pipe?

I don't know about Schedule 40, but I bent a bunch of 1" ID 1/16" wall
6061 thinwall tube by wrapping it around a 1000 lb drum of
communications cable. Granted, not everyone wants a 20" bend radius
on their parts, but it worked for what I needed (gripping a rubber
ball with a 40" diameter).
