Bending 1 4 Aluminum Sheet

6061 t6 aluminum is tempered and notorious for not bending easily.

Bending 1 4 aluminum sheet.

If you bend anything harder than 5054 aluminum you will need to anneal it by heating along the bend line. Place the fracture line over the edge of a table and bend the overhang slightly downwards. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. If you don t such hard aluminum will crack and break during forming.

This weakens the aluminium and creates a fracture line. The best aluminum alloys for bending come down to series 3xxx and series 5xxx and sometimes series 6xxx. Bend allowance mild sheet steel 90 degree bend allowance bend allowance chart example flat size 2 2 095 3 905. K bf 1 33 for v bending.

Material bend radii and minimum bend size charts please note. K bf 0 33 for edge bending. 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.

T stock thickness. Aluminum melts between 865 and 1 240 degrees f so you obviously can t heat it as much as steel. W part width in direction of bend axis. 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.

From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet. Flip the sheet over and repeat. Ts tensile strength of sheet metal.
