Best Aluminum For Sheet Metal Bending

Depending on the form you re working with.

Best aluminum for sheet metal bending.

Material bend radii and minimum bend size charts please note. The best series for forming and thus for bending are the alloy series 3xxx 5xxx and in some cases 6xxx. The best aluminum alloys for bending come down to series 3xxx and series 5xxx and sometimes series 6xxx. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.

But the question remains the same which alloy is the best product for bending. Clinton aluminum offers a variety of products each covering a wide range of applications and processes. I would avoid using alloys in the 2xxx and 7xxx families because they are so strong and therefore difficult to form. From non heat treatable 3003 and 5052 to the heat treatable 2024 6061 and 7075 you have many options from which to choose.

Proper bending can be done with annealing the aluminum first although it s not an ideal candidate for formed parts. From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition.

When bending large sheets your best bet is to use a metal bending brake or to improvise one using a sturdy tabletop and a length of scrap wood.

Miserable to bend cracking is very common and cold bending will always weaken the metal. 1 bending sheet aluminum with a bending brake 2 shaping small pieces with an arbor press 3 tooling aluminum by hand. Highly formable and one of the best kinds of aluminum to bend. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.

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. For small or irregularly shaped. 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. We re having trouble bending 6061 t6 aluminum without cracking and i was wondering if you could give us a few pointers.
