Good Aluminum Sheet For Bending

It gives you design flexibility integrated functions good aesthetics and complex geometries you can also choose between different bending processes such as roller bending press bending draw bending and stretch bending.

Good aluminum sheet for bending.

Series 5xxx are the aluminum magnesium alloys. Heavy gauge aluminum bars or rods must be heat bent using an acetylene torch and vice. This will give you a nice bend. The best aluminum alloys for bending come down to series 3xxx and series 5xxx and sometimes series 6xxx.

Highly formable and one of the best kinds of aluminum to bend. 6061 t6 aluminum is tempered and notorious for not bending easily. From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. 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. Place the fracture line over the edge of a table and bend the overhang slightly downwards. That s the ideal anyway but the reality is that many parts arrive at the press brake in a less than ideal state. A bending brake will be best suited for shaping flat square sheets of light gauge aluminum.

The alloy 5052 h32 may bend well enough for my use and shows about 50 higher tensile and yield. Grain direction bend line should go across the grain for the best bend having said that a typical sharp 90 bend on a piece of 1 8 aluminum sheet should be a minimum 1 8 inside radius use either 3003 or 5052 ideally the bend line should go across the grain. Bending is one of the most common sheet metal fabrication operations. Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.

This weakens the aluminium and creates a fracture line. This is done through the application of force on a workpiece. Series 6xxx are the aluminum magnesium silicon alloys. These heat treatable alloys exhibit great strength good corrosion resistance and ease of formability.

Proper bending can be done with annealing the aluminum first although it s not an ideal candidate for formed parts. The force must exceed the material s yield strength to achieve a plastic deformation. As a general rule the machinability of any aluminum alloy is inversely proportional to its formability. The bending process for aluminium is useful and cost effective.

They exhibit a very good combination of high strength resistance to corrosion formability and good weldability. This is a highly technical and potentially dangerous process best left to a professional metalworker.
