Bending Aluminum Sheet Curve
π 180 x b x ir k x mt bend allowance ba where b is the angle complementary to your desired bend angle 1 to 180 degrees mt is the thickness of the material ir is the inside radius and k is the k factor.
Bending aluminum sheet curve. Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. Tooling aluminum by hand. Curving or rolling aluminum can be a little bit more difficult than curving or rolling normal carbon steel. If the operator is not familiar with the tendencies of aluminum the material can crack or become deformed.
Bending is one of the most common sheet metal fabrication operations. Make sure the first bend mark lines up exactly with the curve in the form so that the bending will begin in the right spot. Shaping small pieces with an arbor press. Buy or rent an arbor press online or at your area home.
Using protective gloves hold the free end of the metal sheet with one hand and with the other hand use a mallet or hammer to begin bending the sheet down and around the curved radius of the wood form. The force must exceed the material s yield strength to achieve a plastic deformation. Although there are many different grades and tempers of aluminum two of the most frequently worked with are 6061 t6 and 6063 t52. Purchase a metal bending brake online or at your local.
