### Capacity chart for air bending

The given data has been calculated based upon bending material with a tensile strength of δb=420^{ }MPa over a length of 1m.

### Internal radius R

The internal radius R corresponds to approximate 16% of the die opening V.

### Recommended die opening V for air bending

Material thickness (t) | 0.5~2.5mm | 3~8mm | 9~10mm | >12mm |
