Minimum Bend Radius Aluminum Sheet

But for harder materials e g.

Minimum bend radius aluminum sheet.

The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.

Minimum inside bend radius for sheet metal recommended inside bend radius for sheet metal parts should be equal to material thickness. 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. 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. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.

Bend radii minimum bend sizes. 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. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

The minimum bend radius data shown in these charts is measured to the inside of the bend. The minimum inside bend radius is even larger when bending with the grain. In steel between 0 5 and 0 8 in. The problem with bending too tightly.

Use this document to choose values that are both manufacturable and meet your needs. Radii for various thicknesses expressed in terms of thickness t. Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in. 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.

We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. 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 steel and aluminum. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

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