Minimum Bend Radius Sheet Metal Chart

Bend radii and minimum bends are limited to certain values or ranges which are determined by the equipment and tooling combinations available to the manufacturer.

Minimum bend radius sheet metal chart.

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. Material bend radii and minimum bend size charts. We recommend 5052 h32 for aluminum chassis projects. Being able to read a bend force chart is crucial for any brake press operator and sheet metal engineer.

The first column of the chart gauge is the thickness of the sheet metal being bent. The gauge inside radius die opening and minimum flange length are all interconnected through different equations and relationships the air bend force chart organizes these variables and points the way towards the ideal setup. Most aluminum requires considerations to ensure any bending is done using a large enough radius to ensure the material does not crack. 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 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. When designing sheet metal parts and enclosures it is helpful to use these values as the basis for your design. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. A general guideline the minimum metal bend radius is approximately equal to the material thickness.

In general parts should be designed with a minimum 1t bend radius radius matching the sheet thickness for the simplest setup and to ensure we can form the intended geometry.
