Steel Sheet Metal Minimum Bend Radius

In steel between 0 5 and 0 8 in.

Steel sheet metal minimum bend radius.

The problem with bending too tightly. 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. It is possible to choose other bends if you require but additional lead time and tooling charges may apply.

For example 6061 t6 aluminum is very difficult to bend. Discover all our calculation tools in the calculators section of the top menu. Maximum sheet thickness for all other steel is 6 mm. The minimum inside bend radius is even larger when bending with the grain.

The tables below show bend radii and minimum bend sizes for materials and tooling combinations stocked by protocase. Aluminum 5052 or 3003. 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. Maximum weight is 40 kg. 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.

Maximum sheet thickness for aluminum and stainless steel is 6 mm. This calculator predicts what the minimum bend radius should be to avoid chacking or orange peeling on the outside radius of the bend. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts. Maximum dimensions are 2980 x 1200 mm.

If a piece of material is bent too tightly problems can occur. A general guideline the minimum metal bend radius is approximately equal to the material thickness. Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel. It requires an inside bend radius of at least 6x the material thickness.

A sharp bend will always be less than a minimum bend radius but a minimum bend radius does not need to be sharp. 5052 h32 aluminum bends in about the same way as mild steel. 3003 h14 is extremely ductile. 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.

The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. These dimensions are all in relation to a 90 angle. If the product contains one or more sharp bends use the dimensions from the sharp tables for all bends in. The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
