Bending Aluminium Sheet Metal

Place the fracture line over the edge of a table and bend the overhang slightly downwards.

Bending aluminium sheet metal. 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. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. 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. In this post we ll explain it to you.

Bending is one of the most common sheet metal fabrication operations. Material bend radii and minimum bend size charts please note. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.

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. The force must exceed the material s yield strength to achieve a plastic deformation. 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. Proper bending can be done with annealing the aluminum first although it s not an ideal candidate for formed parts.

When an operator sees aluminum 5052 or even better yet aluminum 3003 on the part prints it s probably going to be a much better day. Which aluminum alloy bends the best is a a common question customers want the answer to. This is done through the application of force on a workpiece. This weakens the aluminium and creates a fracture line.

Miserable to bend cracking is very common and cold bending will always weaken the metal. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. A bending brake is a specialized metalworking tool used to create precise linear bends and folds in light gauge sheet metals like the kind used to make flashing for doors windows and roofs. Simple sheet metal bender using a hand roller clamps and plywood.

Purchase a metal bending brake online or at your local hardware store. In high purity forms aluminum is soft and ductile.
