Aluminum 6061 bend radius sheet metal.
Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.
When you are forming aluminum if the radius is sharp small in relation to the material thickness you will overwork the material making it harder more brittle and much more likely to fail.

If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured.
Clinton aluminum offers a variety of products each covering a wide range of applications and processes.
Still if you want to avoid cracking abide by the minimum bend radius in 0 25 in thick 6061 t6 which is quite large see figure 3 and avoid bending acute angles.
Say you get a print that says you need to bend a part to an external angle of 100 degrees that s an internal angle of just 80 degrees.
Bending transverse to rolling direction.
T thickness in mm.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
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.
Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.
Radii for various thicknesses expressed in terms of thickness t.
The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.
But the question remains the same which alloy is the best product for bending.
