Is 6063-T6 Pipe More Bendable Than 6061-T6?

摘要

According to Table 1-8 of Forming and Machining Aluminum, the approximate minimum centerline bend radius is 4.25" for both 6061-T6 and 6063-T6 pipes with 2" outside diameters and 0.120" wall thicknesses, suggesting that 6063-T6 also may have failed in your process. For greater bendability 6061-T4 or 6063-T4 pipes of the same size could be considered, as these are listed as having 3.375" minimum centerline bend radii. After bending, the pipes could be strengthened by artificial aging at 350°F. (Note all bend radius values assume use of a fully tooled draw-bending machine and ideal bending conditions, i.e., proper design and alignment of tools, smooth machine operation, and proper lubrication.)
