Bend Radius Copper Sheet

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.

Bend radius copper sheet.

If a piece of material is bent too tightly problems can occur. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. 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. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

The problem with bending too tightly. It is normally expressed in terms of multiples of the material thickness e g. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. For steel the factor is 1. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

In this case the minimum radius equals the respective sheet thickness. But for harder materials e g. The most common problem with bending a piece of sheet metal too tightly is. 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.

If copper has to be bent a factor of 1 5 must be used. First we must start with the k factor. If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance.

What is the minimum radius. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material. We want to know the final length of the detail. If the punch nose radius.

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. Recommended inside bend radius for sheet metal parts should be equal to material thickness.
