It is possible to choose other bends if you require but additional lead time and tooling charges may apply.
Steel sheet metal minimum bend radius.
Discover all our calculation tools in the calculators section of the top menu.
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.
5052 h32 aluminum bends in about the same way as mild steel.
Maximum weight is 40 kg.
If a piece of material is bent too tightly problems can occur.
For example 6061 t6 aluminum is very difficult to bend.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Here again a minimum bend radius is not necessarily the same thing as a sharp bend.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
Maximum sheet thickness for all other steel is 6 mm.
The minimum inside bend radius is even larger when bending with the grain.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
Bend radii minimum bend sizes.
Use this document to choose values that are both manufacturable and meet your needs.
Recommended minimum bend radius for metal bending stainless steel and aluminum.
In steel between 0 5 and 0 8 in.
This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
These dimensions are all in relation to a 90 angle.
The following tables showing the minimum bend radius allowable in air bending process for aluminum and steel or stainless steel.
Aluminum 5052 or 3003.
3003 h14 is extremely ductile.
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.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
A general guideline the minimum metal bend radius is approximately equal to the material thickness.
If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in.
The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase.
Thick grade 350 and 400 may have a minimum bend radius of 2 5 times the material thickness when transverse bending while longitudinal bending may require a minimum bend radius that s 3 75 times the material thickness see figure 1.
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.
The problem with bending too tightly.
Maximum sheet thickness for aluminum and stainless steel is 6 mm.
It requires an inside bend radius of at least 6x the material thickness.
