Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.
Bending 6061 t6 aluminum sheet.
When moving up to t4 and t6 tempers however bending ability tends to decrease.
Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
The 6061t6 aluminum sheet can be bent but the hardness of the t6 temper is high.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in.
Say you re bending 0 25 in thick 6061 t6 aluminum to a 100 degree external angle 80 degree internal angle.
Die opening with a relieved profile.
6061 aluminum sheet plate offers a combination of higher strength good corrosion resistance and machinability making the 6061 grade the most widely used aluminum sheet and plate grade available for all types of fabrication projects the general purpose 6061 aluminum sheet plate is heat treatable resists cracking due to stress and is easy to weld and machine but limited on formability.

To our valued customers.
Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
The temper designations mainly have 6061 t4 t451 al 6061 t6 6061 t651 etc.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
This site should not be used to determine if a.
In the annealed condition it can be used for bending since the difference between yield and tensile strength is 10 ksi and elongation is up to 18.
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.
Here the alloy is 6061 and the temper is t6 meaning the alloy has been thermally treated.
To make this easier you d start with your 6061 material in the soft t 0 state.
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.
The main alloying elements are magnesium mg and silicon si.
In contrast the 6061 o aluminum sheet is more suitable for bending but because it is too soft basically 6061 aluminum sheet with o soft temper is seldom used for bend.
You d probably air bend by using a 3 0 in.
It is one of the most widely used alloys.
The data provided on our website has been vetted to the best of our availabilities.
6061 aluminum alloy al 6061 t6 6061 t651 6061 t4 al 6061 aluminum alloy is a general purpose structural alloy developed by alcoa in 1935.
