Bending 125 Aluminum Sheet

Bending is a delicate and demanding process most of the time and common fabricating processes require a degree of formability that make your choice of proper alloy critical.

Bending 125 aluminum sheet.

The other thing to remember is that in terms of sheet metal equipment the force required goes up with the square of the increase in thickness. I have a 0 984 in. If bending along the grain you want closer to the bigger numbers and across you can bend to a smaller radius. 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.

Some other alloys of aluminum are softer. In high purity forms aluminum is soft and ductile. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. Die and a 0 03 in.

This will give you a nice bend. Many times when people say oh yeah i bend aluminum all the time they are talking about aluminum that is 3003 and its tensile is half that of 5754. 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. If you search for aluminium bend radius you will find that 6061 t6 should be bent with a minimum bend radius of 1 1 2 to 3 times the sheet thickness.

Which aluminum alloy bends the best is a a common question customers want the answer to. Aluminum sheet metal comes in a variety of thicknesses and weights in many different grades. Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6. Place the fracture line over the edge of a table and bend the overhang slightly downwards.

This weakens the aluminium and creates a fracture line. To define the bend region and reduce the force required to bend a part out of sheet metal down to something you can handle without a brake press slots can be cut at the bending line to. Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t. Ryerson offers heat treatable aluminum sheet grades like the popular 6061 aluminum alloy that can be used for commercial applications that require strength corrosion resistance and machinability as well as non heat treatable grades when formability and weldability are priorities.

Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal. I came across a bending issue that has me completely baffled. Material bend radii and minimum bend size charts please note. In this post we ll explain it to you.
