Say you re bending 0 25 in thick 6061 t6 aluminum to a 100 degree external angle 80 degree internal angle.
Bending aluminum sheet 3 16.
Let s consider a challenging job.
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.
I have a piece of 8 5 wide 3 16 thick 5052 aluminium that needs several bends.
A bending brake will be best suited for shaping flat square sheets of light gauge aluminum.
This is one of the most versatile of the heat treatable family of alloys.
This is a highly technical and potentially dangerous process best left to a professional metalworker.
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.
Material bend radii and minimum bend size charts please note.
Heavy gauge aluminum bars or rods must be heat bent using an acetylene torch and vice.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.
The largest angle is only 40 degrees.
To make this easier you d start with your 6061 material in the soft t 0 state.
When moving up to t4 and t6 tempers however bending ability tends to decrease.
Part gets bent from 180 degrees to 140 degrees i just tried this on a small sheet metal type brake but it was trying to pry open the brake.
