Copper Sheet Bending Radius

We want to know the final length of the detail.

Copper sheet bending radius. 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. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. The minimum bend radius is the radius below which an object should not be bent. Bend radii minimum bend sizes.

To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. Another way to determine the k factor is by following the rule of thumb. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. 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.

Use this document to choose values that are both manufacturable and meet your needs. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Each material to be worked also has its own conversion factor. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

In this case the minimum radius equals the respective sheet thickness. What is bending radius and minimum bending radius. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. First we must start with the k factor.

For steel the factor is 1. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. You can check full details in this post. The minimum bend radius data shown in these charts is measured to the inside of the bend.

If copper has to be bent a factor of 1 5 must be used. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. Bend radius is the minimum radius a pipe cable wire sheet cable tube or hose can bend without damaging it including kinking. The smaller the radius the greater is the flexibility of the material.
