Bending Aluminium Sheet

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.

Bending aluminium sheet.

Material bend radii and minimum bend size charts please note. This weakens the aluminium and creates a fracture line. 6061 t6 aluminum is tempered and notorious for not bending easily. In high purity forms aluminum is soft and ductile.

In this post we ll explain it to you. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Miserable to bend cracking is very common and cold bending will always weaken the metal. This is a highly technical and potentially dangerous process best left to a professional metalworker.

Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. Proper bending can be done with annealing the aluminum first although it s not an ideal candidate for formed parts. Highly formable and one of the best kinds of aluminum to bend. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.

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. Place the fracture line over the edge of a table and bend the overhang slightly downwards. We re having trouble bending 6061 t6 aluminum without cracking and i was wondering if you could give us a few pointers. Which aluminum alloy bends the best is a a common question customers want the answer to.

A bending brake will be best suited for shaping flat square sheets of light gauge aluminum. 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. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Heavy gauge aluminum bars or rods must be heat bent using an acetylene torch and vice.

From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. Bending is one of the most common sheet metal fabrication operations. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.
