Minimum Bend Radius Aluminum Sheet

Use this document to choose values that are both manufacturable and meet your needs.

Minimum bend radius aluminum sheet.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may require a minimum bend radius that s 3 75 times the material thickness see figure 1. Bend radii minimum bend sizes.

Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. The minimum inside bend radius is even larger when bending with the grain. Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.

The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered. The minimum bend radius data shown in these charts is measured to the inside of the bend. Minimum inside bend radius for sheet metal recommended inside bend radius for sheet metal parts should be equal to material thickness. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Per the aluminum association inc. In steel between 0 5 and 0 8 in. If a piece of material is bent too tightly problems can occur. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.

Radii for various thicknesses expressed in terms of thickness t. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

But for harder materials e g. Recommended minimum bend radii for steel and aluminum. Table 1 preferred recommended 90 degree bend radii for various sheet metals. O 0 0 0 1t 1t 1t 11 2t 2t t4 0 0 1t 11 2 t21 2 3t 31 2t 4t t6 1t 1t 11 2t 21 2t 3t 31 2 t41 2 5t.

Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
