The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Minimum bending radius for aluminum sheet metal.
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.
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.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
3003 h14 is extremely ductile.
Radii for various thicknesses expressed in terms of thickness t.
For example 6061 t6 aluminum is very difficult to bend.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
At the minimum draw an internal radius of 0 5 sheet thickness in order to prevent problems with corners.
Sophia will adjust the radii drawn in order to retain the shape of the final product.
Per the aluminum association inc.
It requires an inside bend radius of at least 6x the material thickness.
5052 h32 aluminum bends in about the same way as mild steel.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
The internal radius is determined by the tools in conjunction with the material properties.
Bend radii minimum bend sizes.
Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.
Let s say i have a 2 mm thick sheet and i want to bend it.
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.
Use this document to choose values that are both manufacturable and meet your needs.
