Bending Aluminium Alloy Sheet

In other words if you re bending 1 8 sheet use a tool with a 1 8 radius to form the inside of the bend.

Bending aluminium alloy sheet.

The aluminum series ability to bend tends to decrease as you move down the list of tempers from annealed to t4 and t6. In this post we ll explain it to you. Make sure the bar is seated firmly inside the frame. 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.

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 versatile heat treatable alloys. For most applications with stainless steel or aluminum you can get away with a zero radius bend on anything under 0 050 thick. The best aluminum alloys for bending come down to series 3xxx and series 5xxx and sometimes series 6xxx. Bending these tempered alloys is not impossible but it is very difficult and will most likely require large bend radii to avoid cracking on the outside of the bend.

Which aluminum alloy bends the best is a a common question customers want the answer to. In high purity forms aluminum is soft and ductile. Then place the clamp bar back down on top of the aluminum crosswise. When you release the handle the bent material will spring back to 90 not 85.

The idea of adding an angle 5 degrees past 90 is so that you can bend past 90 to allow for the spring back. Insert your aluminum sheet into the brake beneath the removable clamp bar.
