Bending 125 Aluminum Sheet

If you search for aluminium bend radius you will find that 6061 t6 should be bent with a minimum bend radius of 1 1 2 to 3 times the sheet thickness.

Bending 125 aluminum sheet.

Place the fracture line over the edge of a table and bend the overhang slightly downwards. The force must exceed the material s yield strength to achieve a plastic deformation. 6061 t6 aluminum is tempered and notorious for not bending easily. After a few wiggles the sheet will fracture along the cut line leaving a clean break as shown in the above photos.

In high purity forms aluminum is soft and ductile. 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. We re having trouble bending 6061 t6 aluminum without cracking and i was wondering if you could give us a few pointers. Then place the clamp bar back down on top of the aluminum crosswise.

Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Insert your aluminum sheet into the brake beneath the removable clamp bar. 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. To define the bend region and reduce the force required to bend a part out of sheet metal down to something you can handle without a brake press slots can be cut at the bending line to. Your 125 thickness will need a radius of 187 to 375 on the inside of the bend. If bending along the grain you want closer to the bigger numbers and across you can bend to a smaller radius.

Make sure the bar is seated firmly inside the frame. From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. 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. With care and patience full size sheets of aluminium can be cut using this method.

Bending is one of the most common sheet metal fabrication operations. In this post we ll explain it to you. Material bend radii and minimum bend size charts please note. Create a long fracture line then progressively bend the sheet from one end to to the other.
