Sheet Metal Minimum Bend Radius Material

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.

Sheet metal minimum bend radius material.

It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. However it is important to know that this is just a broadly applicable rule of thumb you can follow for making bends in steel. The minimum bend radius data shown in these charts is measured to the inside of the bend. Aluminum 5052 or 3003.

Minimum sheet metal flange bend length 3 x sheet thickness bend radius minimum hole diameter guidelines small sized punch are more prone to failure during sheetmetal punching operation. Therefore for softer materials the recommended minimum hole diameter is equal to sheet thickness. The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel. So if the metal plate is 75 thick you would multiply 4 x 75 3 so your minimum inside bend radius would be roughly 3 times the thickness of the material in this case or 2 25.

Stainless steel and aluminum a general guideline the minimum metal bend radius is approximately equal to the material thickness. Bend radii minimum bend sizes.
