It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
Minimum bend radius aluminum sheet.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
Bend radii minimum bend sizes.
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.
Per the aluminum association inc.
The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in.
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.
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.

Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
If a piece of material is bent too tightly problems can occur.
Use this document to choose values that are both manufacturable and meet your needs.
Minimum inside bend radius for sheet metal recommended inside bend radius for sheet metal parts should be equal to material thickness.
Table 1 preferred recommended 90 degree bend radii for various sheet metals.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
But for harder materials e g.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.
In steel between 0 5 and 0 8 in.
Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.
Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.
