Bend Radius Copper Sheet

If copper has to be bent a factor of 1 5 must be used.

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. 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. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart.

If the punch nose radius. The problem with bending too tightly. 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. What is the minimum radius.

In this case the minimum radius equals the respective sheet thickness. 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. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be.

But for harder materials e g. 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. Sharp inside bend radius in sheetmetal parts can cause material flow problems in soft material and fracturing in hard material.

It is normally expressed in terms of multiples of the material thickness e g. We want to know the final length of the detail. If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.

First we must start with the k factor. The most common problem with bending a piece of sheet metal too tightly is. For steel the factor is 1. Crca inside bend radius equal to 0 65 times of sheet thickness is also enough.

The minimum bend radius data shown in these charts is measured to the inside of the bend. Recommended inside bend radius for sheet metal parts should be equal to material thickness.
