Here s a good rule of thumb for most materials.

How to bend aluminium sheet metal.

Let s consider a challenging job. Cut the section of metal out or otherwise prepare the metal to be bent by removing any burrs or sharp edges. You d probably air bend by using a 3 0 in. In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend.

Then place the clamp bar back down on top of the aluminum crosswise. Monkeys spinning monkeys by kevin macleod. It is important to make sure that the sheet is properly pushed onto the wipe die. The inside bend radius should be equal to the thickness of the material that you re forming.
