The problem with bending too tightly.
Steel sheet metal minimum bend radius.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend.
Recommended minimum bend radius for metal bending stainless steel and aluminum.
If a piece of material is bent too tightly problems can occur.
It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
3003 h14 is extremely ductile.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
5052 h32 aluminum bends in about the same way as mild steel.
Maximum dimensions are 2980 x 1200 mm.
The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel.
This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
For example 6061 t6 aluminum is very difficult to bend.
These dimensions are all in relation to a 90 angle.
Bend radii minimum bend sizes.
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 minimum bend radius data shown in these charts is measured to the inside of the bend.
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.
Maximum sheet thickness for aluminum and stainless steel is 6 mm.
Aluminum 5052 or 3003.
The minimum inside bend radius is even larger when bending with the grain.
In steel between 0 5 and 0 8 in.
Here again a minimum bend radius is not necessarily the same thing as a sharp bend.
A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
It requires an inside bend radius of at least 6x the material thickness.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
Use this document to choose values that are both manufacturable and meet your needs.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
Maximum weight is 40 kg.
