Copper Sheet Bending Radius

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.

Copper sheet bending radius.

Use this document to choose values that are both manufacturable and meet your needs. Bend radii minimum bend sizes. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. First we must start with the k factor.

For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. The minimum bend radius data shown in these charts is measured to the inside of the bend. 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 smaller the radius the greater is the flexibility of the material.

You can check full details in this post. In this case the minimum radius equals the respective sheet thickness. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. 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. Bend radius is the minimum radius a pipe cable wire sheet cable tube or hose can bend without damaging it including kinking. 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.

Another way to determine the k factor is by following the rule of thumb. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. What is bending radius and minimum bending radius. The minimum bend radius is the radius below which an object should not be bent.

The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. We want to know the final length of the detail. Each material to be worked also has its own conversion factor. For steel the factor is 1.
