Which aluminum alloy bends the best is a a common question customers want the answer to.
Bending 125 aluminum sheet.
Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
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.
Aluminum sheet metal comes in a variety of thicknesses and weights in many different grades.
With the aid of a straight edge and a sharp knife score both sides of the aluminium sheet.
Your 125 thickness will need a radius of 187 to 375 on the inside of the bend.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
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.
If bending along the grain you want closer to the bigger numbers and across you can bend to a smaller radius.
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.
This weakens the aluminium and creates a fracture line.
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.
I came across a bending issue that has me completely baffled.
I have a 0 984 in.
Die and a 0 03 in.
Material bend radii and minimum bend size charts please note.
We were working with 0 125 in thick 6061 t6 aluminum but we were experiencing cracking problems so we switched to 1100 o aluminum with a specified tensile strength of just 13 000 psi.
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.
In high purity forms aluminum is soft and ductile.
Some other alloys of aluminum are softer.
This will give you a nice bend.
In this post we ll explain it to you.
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.
Sheet aluminium can be cut without the need for a guillotine or tin snips which tend to deform the metal.
