Minimum Bending Radius For Aluminum Sheet Metal

Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.

Minimum bending radius for aluminum sheet metal. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Discover all our calculation tools in the calculators section of the top menu. 5052 h32 aluminum bends in about the same way as mild steel. Per the aluminum association inc.

Bend radii minimum bend sizes. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. The minimum bend radius data shown in these charts is measured to the inside of the bend. For example 6061 t6 aluminum is very difficult to bend.

Use this document to choose values that are both manufacturable and meet your needs. Let s say i have a 2 mm thick sheet and i want to bend it. Radii for various thicknesses expressed in terms of thickness t. The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.

Sophia will adjust the radii drawn in order to retain the shape of the final product. Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.

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. Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6. The internal radius is determined by the tools in conjunction with the material properties.

3003 h14 is extremely ductile. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. At the minimum draw an internal radius of 0 5 sheet thickness in order to prevent problems with corners.

To keep it simple i also use a 2 mm inside radius. 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.
