Minimum Bend Radius Aluminum Sheet

Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.

Minimum bend radius aluminum sheet.

Aluminum minimum bend radii for 90 degree cold forming of sheet and plate. Table 1 preferred recommended 90 degree bend radii for various sheet metals.

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. 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. Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in. In steel between 0 5 and 0 8 in.

Recommended minimum bend radii for steel and aluminum. Per the aluminum association inc. Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. Use this document to choose values that are both manufacturable and meet your needs.

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. The problem with bending too tightly. 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. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Bend radii minimum bend sizes. The minimum inside bend radius is even larger when bending with the grain. The minimum bend radius data shown in these charts is measured to the inside of the bend.

If a piece of material is bent too tightly problems can occur. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.

But for harder materials e g.
