Copper Sheet Bending Radius

For steel the factor is 1.

Copper sheet bending radius.

Types of copper and properties. A soft metal can be especial ly troublesome when bending tubing smaller than 3 4 inch in diameter a tight radius bend for copper is any bend with a radius equal to or less than approximately 2 5 times the tube s od that s 2 5d in tube fabricating jargon. And by having t and the sheet thickness t we can calculate the k factor as follow. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

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. As the extensibility ductility of harder steels is lower than that of softer steels the minimum bending radius of materials with high strength is also larger than for less strong steel. Most frequently expensive sheet metal bending tools called brakes are used to bend sheet metal but you can also complete this task without one. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

Refer to table s for your choice of material. If copper has to be bent a factor of 1 5 must be used. To use the tables below. It consists of 99 9 percent copper and is available in six tempers designated by astm b370 as.

The force must exceed the material s yield strength to achieve a plastic deformation. Bending angles greater than 90 degrees. If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. 060 soft h00 cold rolled h01 cold rolled high yield h02 half hard h03 three quarter hard and h04 hard.

Also known as press braking flanging die bending folding and edging this method is used to deform a material to an angular shape. The d of bend is the result of dividing the bend s centerline radius. Bending sheet metal by hand is a manageable task if the piece of sheet metal is small and thin enough to handle. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Bending is one of the most common sheet metal fabrication operations. Like previous scenarios let s start by calculating leg length 1. Since commercial sheet metal bending can be done with less concern for stresses caused during forming operation the radius can be near zero for thin sheet metal. The minimum bend radius data shown in these charts is measured to the inside of the bend.

The copper most commonly used for sheet and strip applications complies with astm b370. In this case the minimum radius equals the respective sheet thickness.
