This is 6061 t6. What kind of tubing do I need to bend. My local supplier only has 6061 t-6 in these sizes, and where can I get it from? Im on the east coast? Any help would be appriciated. These will be used on a atv bumpers nerf bars and grab bar.
Take a length of tube and your Oxy/Actl torch.
Light only the Acetylene get a nice fat flame with lots of suet Anyway you coat the tube black all around. Then turn on the O2 and adjust to a neutral flame. then heat the tube evenly all the way around until the black starts to burn off and continue to chase the black away moving around and along the tube. You only want to heat till the suet... evaporates (oxidizes) no hotter.
Let cool in still air.
Now you have 6061-T0 or annealed.
Dead soft aluminum is sticky, I would recommend a liberal amount of slickum for sure on the wiper die.
