The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.
Minimum bend radius aluminum sheet metal.
Radii for various thicknesses expressed in terms of thickness t.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
3003 h14 is extremely ductile.
Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.
For example 6061 t6 aluminum is very difficult to bend.
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.
Bend radii minimum bend sizes.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Per the aluminum association inc.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
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.
5052 h32 aluminum bends in about the same way as mild steel.
Use this document to choose values that are both manufacturable and meet your needs.
Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in.
Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.

Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
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.
It requires an inside bend radius of at least 6x the material thickness.
