Easy Way To Bend Aluminium Sheet

This is generalizing of course as there are ways to form 6061.

Easy way to bend aluminium sheet.

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. If you can make it to the end without problem then just follow your own steps. When working with sheet metal one particularly useful piece of equipment is the brake. Metal shops have brakes mounted at different angles with automated braking arms however it is possible to bend sheet metal at home without the use of a brake.

With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. Insert your aluminum sheet into the brake beneath the removable clamp bar. In this post we ll explain it to you. Next place the wood parallel and slightly behind the bending line.

The two m10 bolts in the top are to clamp the sheet between the backstop and the base. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. Finally bend the sheet up by hand to the angle desired. Clamp the wood on top of the metal to the workbench.

Make sure the bar is seated firmly inside the frame. Every time you do a bend mark the spot with a number. The aluminum series ability to bend tends to decrease as you move down the list of tempers from annealed to t4 and t6. Ideally part designers should know that when it comes to aluminum grades 3003 and 5052 will bend 6061 will not.

Lift the clamp bar away from the rear of the brake frame and slide the sheet in perpendicularly to the direction you want to bend it. A brake is a device that allows you to bend a piece of sheet metal at a particular angle. Which aluminum alloy bends the best is a a common question customers want the answer to. The idea of adding an angle 5 degrees past 90 is so that you can bend past 90 to allow for the spring back.

In some cases as with thicker sheet of metal you may need to use a sheet metal brake to apply your bend. Either way there are a few shapes that just aren t very practical for most bending tools. In high purity forms aluminum is soft and ductile. When you release the handle the bent material will spring back to 90 not 85.

How to bend sheet metal without a brake. Mark a bend line and place the sheet metal on the edge of your bench. This weakens the aluminium and creates a fracture line. Then place the clamp bar back down on top of the aluminum crosswise.

The easiest way to do this is to just cut off a little strip of metal to use as a test piece.
