Minimum Bending Radius Copper Sheet

Per the aluminum association inc.

Minimum bending radius copper sheet.

The minimum bend radius is the radius below which an object should not be bent. In steel between 0 5 and 0 8 in. 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. Bend radius is the minimum radius a pipe cable wire sheet cable tube or hose can bend without damaging it including kinking.

Material bend radii and minimum bend size charts please note. The first uses bending springs and the second a. To keep it simple i also use a 2 mm inside radius. In this case the minimum radius equals the respective sheet thickness.

The minimum inside bend radius is even larger when bending with the grain. Most copper pipe tube can be readily bent and two main methods are employed. Radii for various thicknesses expressed in terms of thickness t. Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. As a general rule the minimum bending radius for copper bar is equal to the thickness of the bar. Let s say i have a 2 mm thick sheet and i want to bend it. 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.

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. What is bending radius and minimum bending radius. Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend. If copper has to be bent a factor of 1 5 must be used.

The smaller the radius the greater is the flexibility of the material. Tube and pipe bending. The minimum bend radius data shown in these charts is measured to the inside of the bend. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.

For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. 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. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. You can check full details in this post.

C opper and coppe r alloy bar can be bent using standard bending methods.
