Can anyone tell me where I can find reliable numbers for the minimum bend radius on large 6061-T6 aluminum tube or pipe, something like 5 or 6 inch diameter, and at different wall thicknesses? I need to put a bend in the frame of an experimental off-road vehicle. I know I can cut and weld, but there are also areas where I want the curve. I figure someone in aviation might know this.
Thaanks in advance -
