The minimum bend radius data shown in these charts is measured to the inside of the bend.
Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried.
1 radii listed are minimum recommended for bending sheets and plates without fracturing in a standard press brake with air bend dies.
T thickness in mm.
If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured.
That is it gets stronger and harder by working bending it.
Clinton aluminum offers a variety of products each covering a wide range of applications and processes.
Recommended minimum bend radii for 90 degree cold forming of sheet plate.
Radii for various thicknesses expressed in terms of thickness t.
Just like all sheet metal aluminum work hardens during the forming process.
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.
Specifing a bend radius from here will help prevent hair line cracks.
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.
From non heat treatable 3003 and 5052 to the heat treatable 2024 6061 and 7075 you have many options from which to choose.
Per the aluminum association inc.
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.
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.
