Aluminum Grade For Sheet Metal Sharp Bends

If your project does not have any physical or structural demands and the aesthetics are not important then almost any aluminum grade will do the job.

Aluminum grade for sheet metal sharp bends.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. A simple metal folder suitable for making small metal boxes and chassis is also described. This instructable shows how sheet aluminium may be cut using nothing but a knife and a metal straight edge. Material bend radii and minimum bend size charts please note.

When you are forming aluminum if the radius is sharp small in relation to the material thickness you will overwork the material making it harder more brittle and much more likely to fail. In most cases it can be difficult to choose the correct aluminum grade for your intended application. 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. Miserable to bend cracking is very common and cold bending will always weaken the metal.

The minimum bend radius data shown in these charts is measured to the inside of the bend. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. In this post we ll explain it to you. Which aluminum alloy bends the best is a a common question customers want the answer to.

Proper bending can be done with annealing the aluminum first although it s not an ideal candidate for formed parts. This is done through the application of force on a workpiece. Just like all sheet metal aluminum work hardens during the forming process. In high purity forms aluminum is soft and ductile.

That is it gets stronger and harder by working bending it. The aluminum series ability to bend tends to decrease as you move down the list of tempers from annealed to t4 and t6. Aluminum is a common metal used for both industrial and non industrial applications. This is generalizing of course as there are ways to form 6061.

Bending is one of the most common sheet metal fabrication operations. Highly formable and one of the best kinds of aluminum to bend. Ideally part designers should know that when it comes to aluminum grades 3003 and 5052 will bend 6061 will not. Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal.
