I have embarked upon a deceivingly challenging project that involves bending 3/4" thin walled aluminum tubing into circular shapes about 36" in diameter. I'm having a heck of a time finding the right material and was wondering if any experts out there knew from experience what the best aluminum alloy for this application would be? My plan is to pack the tubing with sand and hand bend it cold around a jig.
No announcement yet.
Best aluminum alloy for bending?
