The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

Sheet metal bending radius chart.

Bend allowance mild sheet steel 90 degree bend allowance. 032 18 ga 040 16 ga. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. To use the tables below.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Example flat size 2 2 095 3 905 bend radius 22 ga. Since the pipes are generally secured at one end measure the length of. An air bend force chart or force chart breaks down a number of key components of sheet metal bending in an easy to reference format.

Bend the minimum bend radius data shown in these charts is measured to the inside of the bend. Minimum recommended bend radius chart from american. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force chart organizes these variables and points the way towards the ideal setup. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer. Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.
