Minimum Bending Radius Copper Sheet

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

Minimum bending radius copper sheet.

Let s say i have a 2 mm thick sheet and i want to bend it. Per the aluminum association inc. C opper and coppe r alloy bar can be bent using standard bending methods. What is bending radius and minimum bending radius.

I can now see that the minimum flange length is 8 5 mm for such a bend so i have to keep it in mind when designing. In steel between 0 5 and 0 8 in. In this case the minimum radius equals the respective sheet thickness. The bend radius you select may not be available if the geometry of the part will not allow us to bend with the specific tooling required to achieve that radius.

For steel the factor is 1. The minimum bend radius data shown in these charts is measured to the inside of the bend. You can check full details in this post. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

Bend radius is the minimum radius a pipe cable wire sheet cable tube or hose can bend without damaging it including kinking. Radii for various thicknesses expressed in terms of thickness t. The smaller the radius the greater is the flexibility of the material. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.

Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may require a minimum bend radius that s 3 75 times the material thickness see figure 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. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The minimum inside bend radius is even larger when bending with the grain.

The minimum bend radius is the radius below which an object should not be bent. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. As a general rule the minimum bending radius for copper bar is equal to the thickness of the bar. Most copper pipe tube can be readily bent and two main methods are employed.

The first uses bending springs and the second a. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. 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. Material bend radii and minimum bend size charts please note.
