Minimum Bending Radius Copper Sheet

Bend radii minimum bend sizes.

Minimum bending radius copper sheet.

In this case the minimum radius equals the respective sheet thickness. Minimum sheet metal flange bend length is required to avoid cracks in the bending area. The overall diameter of the cable is given as 2 08 inches in the product catalog. 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 grades.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. According to table 1 the minimum bend radius is found to be six times the cable s overall diameter. For steel the factor is 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.

Radius is the minimum producible inside radius for this material and not the recommended inside radius that you see on the bend allowance chart. The minimum bend radius data shown in these charts is measured to the inside of the bend. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. 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.

Use this document to choose values that are both manufacturable and meet your needs. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Minimum sheet metal flange bend length 3 x sheet thickness bend radius minimum hole diameter guidelines. Multiplying 2 08 inches by six we get 12 48 inches.

If copper has to be bent a factor of 1 5 must be used. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. It s true that the harder and thicker the plate is the greater the minimum bend radius.

It shall be equal to three times of sheet thickness plus bend radius. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
