Bend Radius Copper Sheet

If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured.

Bend radius copper sheet.

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. We want to know the final length of the detail. In this case the minimum radius equals the respective sheet thickness.

If copper has to be bent a factor of 1 5 must be used. For example the minimum bending radius of aluminium is determined by multiplying the sheet thickness by a factor of 2. The minimum bend radius data shown in these charts is measured to the inside of the bend. The most common problem with bending a piece of sheet metal too tightly is.

To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. 0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

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. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough. What is the minimum radius. Recommended inside bend radius for sheet metal parts should be equal to material thickness.

But for harder materials e g. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. If the punch nose radius.

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 normally expressed in terms of multiples of the material thickness e g. If a piece of material is bent too tightly problems can occur. First we must start with the k factor.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
