Copper Sheet Bending Radius

Another way to determine the k factor is by following the rule of thumb.

Copper sheet bending radius. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. If copper has to be bent a factor of 1 5 must be used. The minimum bend radius data shown in these charts is measured to the inside of the bend. Bend radius is the minimum radius a pipe cable wire sheet cable tube or hose can bend without damaging it including kinking.

Use this document to choose values that are both manufacturable and meet your needs. For steel the factor is 1. The smaller the radius the greater is the flexibility of the material. What is bending radius and minimum bending radius.

For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. First we must start with the k factor. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.

In this case the minimum radius equals the respective sheet thickness. The minimum bend radius is the radius below which an object should not be bent. Bend radii minimum bend sizes. 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.

You can check full details in this post. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. For ordinary low carbon steel plate anti rust aluminum plate yellow copper purple copper etc the inner radius 0 2 is no problem but for some high carbon steel hard aluminum super hard aluminum the use 0 2 radius will lead to bending fracture or the outer radius crack. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

We want to know the final length of the detail. 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. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
