The minimum bend radius data shown in these charts is measured to the inside of the bend.
Minimum bend radius aluminum sheet metal.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.
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.

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.
Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in.
The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.
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 bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

3003 h14 is extremely ductile.
5052 h32 aluminum bends in about the same way as mild steel.
Bend radii minimum bend sizes.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
Radii for various thicknesses expressed in terms of thickness t.
For example 6061 t6 aluminum is very difficult to bend.
Bend radii minimum bend sizes.
Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
It requires an inside bend radius of at least 6x the material thickness.
Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.
