The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
Minimum bend radius aluminum sheet metal.
Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.
For example 6061 t6 aluminum is very difficult to bend.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
It requires an inside bend radius of at least 6x the material thickness.

Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
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 where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
When designing sheet metal parts and enclosures it is helpful to use these values as the basis for your design.
Use this document to choose values that are both manufacturable and meet your needs.
3003 h14 is extremely ductile.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.
Per the aluminum association inc.
5052 h32 aluminum bends in about the same way as mild steel.
Bend radii minimum bend sizes.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Bend radii and minimum bends are limited to certain values or ranges which are determined by the equipment and tooling combinations available to the manufacturer.
The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.
Radii for various thicknesses expressed in terms of thickness t.
Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in.
