Re: Wheel Axle Material
I would not be comfortable with 6061 in any application really. This past year we bent 1/2" round 2024 keyed axles. We used 2024 1/2" hex on the gripper which was fine. I plan to go to all 7075 in the future. It's much stronger. Fry Steel has good pricing on 7075 1/2" hex, but it may be a tad oversize. For round axles that you want to fit through bearings easily without any work, precision ground 7075 would be the way to go, but it isn't cheap.
