Aluminum 6061 Bend Radius Sheet Metal

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.

Aluminum 6061 bend radius sheet metal. 2024 t3 1020 1025 4130 ann. 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. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Or yor metal ees 0 9 rier ane p bo ermanton 0 00 99 99 90 fa 90 zzzaicmetalcom 6061 alloy.

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. Radii for various thicknesses expressed in terms of thickness t. But the question remains the same which alloy is the best product for bending. The minimum bend radius data shown in these charts is measured to the inside of the bend.

Here the alloy is 6061 and the temper is t6 meaning the alloy has been thermally treated. Recommended minimum bend radii for 90 degree cold forming of sheet plate. Minimum bend radius xls author. Clinton aluminum offers a variety of products each covering a wide range of applications and processes.

6061 t3 is not recommended for sheet metal work because it will crack on the outside radius once it passes its yield when being processed on a brake press for example. 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. Specifing a bend radius from here will help prevent hair line cracks. If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured.

Aluminum minimum bend radii for 90 degree cold forming of sheet and plate. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. 6061 t6 2 3 3 4 6 8 18 32 aluminum minimum bend radius in 1 32nds of an inch title. Material suppliers have tables that show the approximate minimum inside bend radius for the various alloys the temper condition of each and the minimum allowable inside radius at 90 degrees of bend angle.

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 main alloy ingredients are magnesium and silicon.
