Minimum Bend Radii: The minimum bend radius data shown in these charts is measured to the inside of the bend. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. 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.

How do you calculate the bending radius of a sheet metal

What is the minimum bend radius for sheet metal? Most fabricators of sheet metal parts will require a minimum bend radius on formed objects. The minimum bend radius should be a minimum of ½ of the material thickness, so if the material is 18- gauge or 0.048 thick, then the inside radius would be 0.024, making the outside radius 0.072.
