Radii for various thicknesses expressed in terms of thickness t.
Minimum bend radius aluminum sheet metal.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent.
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.
When designing sheet metal parts and enclosures it is helpful to use these values as the basis for your design.
Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
For example 6061 t6 aluminum is very difficult to bend.
3003 h14 is extremely ductile.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in.
5052 h32 aluminum bends in about the same way as mild steel.
Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.

The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.
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.
Use this document to choose values that are both manufacturable and meet your needs.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
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.

The minimum bend radius data shown in these charts is measured to the inside of the bend.
