Minimum Bend Radius Aluminum Sheet Metal

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.

Minimum bend radius aluminum sheet metal.

The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered. Use this document to choose values that are both manufacturable and meet your needs. 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.

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. Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6. It requires an inside bend radius of at least 6x the material thickness. Bend radii minimum bend sizes.

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. For example 6061 t6 aluminum is very difficult to bend. Per the aluminum association inc.

Aluminum minimum bend radii for 90 degree cold forming of sheet and plate. Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.

Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in. 3003 h14 is extremely ductile. 5052 h32 aluminum bends in about the same way as mild steel. Discover all our calculation tools in the calculators section of the top menu.

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
