Minimum Bending Radius For Aluminum Sheet Metal

3003 h14 is extremely ductile.

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. 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. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Sophia will adjust the radii drawn in order to retain the shape of the final product. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. Radii for various thicknesses expressed in terms of thickness t. Per the aluminum association inc.

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. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. The minimum bend radius data shown in these charts is measured to the inside of the bend.

Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6. 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 internal radius is determined by the tools in conjunction with the material properties. At the minimum draw an internal radius of 0 5 sheet thickness in order to prevent problems with corners.

For example 6061 t6 aluminum is very difficult to bend. 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. 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. The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. To keep it simple i also use a 2 mm inside radius.

Aluminum minimum bend radii for 90 degree cold forming of sheet and plate. Let s say i have a 2 mm thick sheet and i want to bend it.
