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.

Minimum bend radius aluminum sheet metal.

When designing sheet metal parts and enclosures it is helpful to use these values as the basis for your design. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Per the aluminum association inc.

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. Radii for various thicknesses expressed in terms of thickness t. Discover all our calculation tools in the calculators section of the top menu. 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.

3003 h14 is extremely ductile. The minimum bend radius data shown in these charts is measured to the inside of the 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. 5052 h32 aluminum bends in about the same way as mild steel.

Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. Bend radii minimum bend sizes. 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.

Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. Bend radii minimum bend sizes. The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered. Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.

Use this document to choose values that are both manufacturable and meet your needs. Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
