Why does 6061-T6 need a larger bend radius?
6061-T6 is a harder heat-treated aluminum temper and is more crack-prone than softer aluminum alloys when formed tightly.

FAQ
Specific checks for this calculator
Is minimum bend radius the same as V-die radius?
No. Minimum bend radius is a material limit, while the produced air-bend radius depends heavily on the selected V-die opening and tooling.
