Best Aluminum For Sheet Metal Bending

That s the ideal anyway but the reality is that many parts arrive at the press brake in a less than ideal state.

Best aluminum for sheet metal bending.

A bending brake will be best suited for shaping flat square sheets of light gauge aluminum. Hot rolled pickled and oiled 14 to 16 percent. Series 6xxx are the aluminum magnesium silicon alloys. Alloy 5052 has a good resistance to marine atmosphere and salt water corrosion and excellent workability.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. The best aluminum alloys for bending come down to series 3xxx and series 5xxx and sometimes series 6xxx. This is done through the application of force on a workpiece.

These heat treatable alloys exhibit great strength good corrosion resistance and ease of formability. 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 force must exceed the material s yield strength to achieve a plastic deformation. The top 3 aluminum alloys for being are the 3003 which has medium strength and the best cold workability the 5052 which is the highest strength alloy of the more common non heat treatable grades and the 6061 which is one of the more versatile heat treatable alloys.

Its fatigue strength is higher than most other aluminum grades. This is a highly technical and potentially dangerous process best left to a professional metalworker. This is the highest strength alloy of the more non heat treatable grades. Material bend radii and minimum bend size charts please note.

60 ksi tensile cold rolled steel 15 to 17 percent. Bending is one of the most common sheet metal fabrication operations. 5052 h32 soft aluminum the inside radius is between 11 and 13 percent of the die opening. 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.

Heavy gauge aluminum bars or rods must be heat bent using an acetylene torch and vice. 6061 in o condition 18 to 20 percent. 304 stainless steel 20 to 22 percent. 6061 t6 aluminum is tempered and notorious for not bending easily.

The are mainly used in architectural applications.
