  • Aluminumn Tubing???

    I wish to Bend Up and Weld some one and a Half inch Dia. Aluminumn Tubing. What grade of Aluminumn do I purchase and where do you get some? I need Twenty feet or so. I bought a Van Sant Tube Bender and plan on filling tube with sand and then cranking on it. Which Aluminumn doesnt require heat treat after welding? Thanx Everyone for any ideas you have Audrey

    Need a little more info Audrey.

    First, how strong does this need to be? What welding process? How tight a radius? What wall thickness? What surface finish on the final product?

        Your Aluminum supplier can tell you all of this - if they can't look for another one. Depending on what the end product has to do will determine what alloy and process you need to work with. Some alloys have to be tempered and then solution hardened after welding to regain their physical properties. It is not cut & dried.

        Far simpler to say the hell with it and use stainless - its shiney you know!
