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.

Aluminum sheet metal bend radius chart.

The minimum bend radius data shown in these charts is measured to the inside of the bend. Material bend radii and minimum bend size charts please note. Where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. To use the tables below.

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Example flat size 2 2 095 3 905 bend radius 22 ga. If these guidelines are not followed more research and or some form of analysis may be requried.

032 18 ga 040 16 ga. The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Bend allowance mild sheet steel 90 degree bend allowance.

When working with aluminum over sheet metal several variables need to be considered. Preferred recommended 90 degree bend radii for various sheet metals. Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. Refer to table s for your choice of material.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Sheet metal bend radii.
