Removing Bends From Aluminum Sheet

Aluminum is highly malleable which makes it easy to work with but also easy to accidentally bend.

Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. Clamp the wood on top of the metal to the workbench. Mark a bend line and place the sheet metal on the edge of your bench. The mill marks left by the tooth of the rolling mill rolls is parallel to the grain direction.

When working with sheet metal one particularly useful piece of equipment is the brake. If you do inadvertently bend a piece of aluminum don t assume it is ruined and throw it away.

Hand bending without mechanical equipment produces clean bends with a minimal amount of tools. In high purity forms aluminum is soft and ductile. The spacing between the two nuts and bolts determines the maximum width sheet that can be bent. Bending is a delicate and demanding process most of the time and common fabricating processes require a degree of formability that make your choice of proper alloy critical.
