Copper Sheet Bending Radius

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

Copper sheet bending radius. What is bending radius and minimum bending radius. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. 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 bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm.

Bend radius is the minimum radius a pipe cable wire sheet cable tube or hose can bend without damaging it including kinking. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance.

Each material to be worked also has its own conversion factor. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. The minimum bend radius data shown in these charts is measured to the inside of the bend. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Bend radii minimum bend sizes. We want to know the final length of the detail. You can check full details in this post. In this case the minimum radius equals the respective sheet thickness.

Use this document to choose values that are both manufacturable and meet your needs. 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. The minimum bend radius is the radius below which an object should not be bent.

The smaller the radius the greater is the flexibility of the material. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. For steel the factor is 1. 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.
