Bend Radius Copper Sheet

It is normally expressed in terms of multiples of the material thickness e g.

Bend radius copper sheet.

Table 1 preferred recommended 90 degree bend radii for various sheet metals. We want to know the final length of the detail. Cutting copper sheet and plate. 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.

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. 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. As an example if you want to bend 24 gauge sheet metal at a 90 angle the calculation would be. Tube and pipe bending.

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. Most copper pipe tube can be readily bent and two main methods are employed. To ascertain your k factor inside radius and material thickness expressed as a decimal you should use an bend allowance chart. If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured.

It is possible to choose other bends if you require but additional lead time and tooling charges may apply. The first uses bending springs and the second a pipe bending machine. 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.

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. First we must start with the k factor. Specifing a bend radius from here will help prevent hair line cracks.

0 017453 x 90 x 0 020 0 33 x 0 024 0 0438558984 inch bend allowance. If the punch nose radius. Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

As a general rule the minimum bending radius for copper bar is equal to the thickness of the bar. For steel the factor is 1. What is the minimum radius.
