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.

Minimum bend radius aluminum sheet metal.

Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels. 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. 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. Discover all our calculation tools in the calculators section of the top menu.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. 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. Aluminum minimum bend radii for 90 degree cold forming of sheet and plate. Use this document to choose values that are both manufacturable and meet your needs.

Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. 5052 h32 aluminum bends in about the same way as mild steel. It requires an inside bend radius of at least 6x the material thickness.

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 minimum bend sizes. 3003 h14 is extremely ductile. Bend radii minimum bend sizes.

Per the aluminum association inc. The minimum bend radius data shown in these charts is measured to the inside of the bend.
