Minimum Bending Radius For Aluminum Sheet Metal

An inside radius of the material thickness is typical forming practice.

Minimum bending radius for aluminum sheet metal.

Aluminum minimum bend radii for 90 degree cold forming of sheet and plate. Radii for various thicknesses expressed in terms of thickness t. Per the aluminum association inc. Alternatively you can design with any value and we can adjust it for you later in the process.

The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered. Use this document to choose values that are both manufacturable and meet your needs. The max minimum inside radius sheet metal unhardened can be formed on the brake press is 63 x 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.

It cannot be formed tighter without creasing and forming a v shape along the bend. The minimum bend radius data shown in these charts is measured to the inside of the bend. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. 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.

We recommend 5052 h32 for aluminum chassis projects.
