In general parts should be designed with a minimum 1t bend radius radius matching the sheet thickness for the simplest setup and to ensure we can form the intended geometry.
Minimum bend radius sheet metal aluminum.
Use this document to choose values that are both manufacturable and meet your needs.
Bend radii minimum bend sizes.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.
We recommend 5052 h32 for aluminum chassis projects.
Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.
Most aluminum requires considerations to ensure any bending is done using a large enough radius to ensure the material does not crack.

Radii for various thicknesses expressed in terms of thickness t.
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.
