Bending 1 4 Aluminum Sheet

This weakens the aluminium and creates a fracture line.

Bending 1 4 aluminum sheet. W part width in direction of bend axis. Aluminum melts between 865 and 1 240 degrees f so you obviously can t heat it as much as steel. T stock thickness. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one.

Ts tensile strength of sheet metal. 0 060 crs 2 000 2 000 r0 031 aluminum 90 deg. If you don t such hard aluminum will crack and break during forming. With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.

K bf 0 33 for edge bending. Flip the sheet over and repeat. If you d like to know more about bending specific alloys or which alloy is best for your application please contact our sales department by. If you bend anything harder than 5054 aluminum you will need to anneal it by heating along the bend line.

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. 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. From a bending perspective it s always best to bend these parts in an annealed state and then temper them to the correct condition. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.

6061 t6 aluminum is tempered and notorious for not bending easily. Material bend radii and minimum bend size charts please note. Place the fracture line over the edge of a table and bend the overhang slightly downwards. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle.

The best aluminum alloys for bending come down to series 3xxx and series 5xxx and sometimes series 6xxx.
