Bending Aluminium Sheet

We re having trouble bending 6061 t6 aluminum without cracking and i was wondering if you could give us a few pointers.

Bending aluminium sheet.

Heavy gauge aluminum bars or rods must be heat bent using an acetylene torch and vice. A bending brake will be best suited for shaping flat square sheets of light gauge aluminum. In high purity forms aluminum is soft and ductile. Commonly used equipment include box and pan brakes brake presses and other specialized machine presses typical products that are made like this are boxes such as electrical enclosures and rectangular ductwork.

From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. Proper bending can be done with annealing the aluminum first although it s not an ideal candidate for formed parts. In this post we ll explain it to you.

Material bend radii and minimum bend size charts please note. This is a highly technical and potentially dangerous process best left to a professional metalworker. Which aluminum alloy bends the best is a a common question customers want the answer to. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.

The force must exceed the material s yield strength to achieve a plastic deformation. Place the fracture line over the edge of a table and bend the overhang slightly downwards. Bending is one of the most common sheet metal fabrication operations. Miserable to bend cracking is very common and cold bending will always weaken the metal.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius. Bending is a manufacturing process that produces a v shape u shape or channel shape along a straight axis in ductile materials most commonly sheet metal.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Highly formable and one of the best kinds of aluminum to bend. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. 6061 t6 aluminum is tempered and notorious for not bending easily.
