Bend Radius Copper Sheet

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.

Bend radius copper sheet.

But for harder materials e g. In this case the minimum radius equals the respective sheet thickness. For steel the factor is 1. It is the smallest inside bend radius that you can place in a piece of material before the tensile forces on the outside of the bend begin to tear the grains in the material apart.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. 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. It is normally expressed in terms of multiples of the material thickness e g.

If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. Each and every bend in a piece of sheet metal has a certain minimum internal radius that needs to be taken into account when planning the design of a sheet metal form. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. Recommended inside bend radius for sheet metal parts should be equal to material thickness.

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. The most common problem with bending a piece of sheet metal too tightly is. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. First we must start with the k factor.

The problem with bending too tightly. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm.

If a piece of material is bent too tightly problems can occur. What is the minimum radius. If the punch nose radius. If copper has to be bent a factor of 1 5 must be used.

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.
