Aluminum Sheet Metal Bend Radius

The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.

Aluminum sheet metal bend radius. If your bend radius needs to be adjusted a member of engineering design services team will contact you before your design is manufactured. Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. Most angle finders feature two short legs that rotate independently of one another. Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.

Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill. Steel american iron and steel institute. Preferred recommended 90 degree bend radii for various sheet metals. If a piece of material is bent too tightly problems can occur.

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. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. 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. On each leg you ll see a series of markings indicating various angles in relation to the opposing leg.

If these guidelines are not followed more research and or some form of analysis may be requried. The most common problem with bending a piece of sheet metal too tightly is. We want to know the final length of the detail. In our example below a part with flange lengths of 2 and 3 with an inside radius of 250 at 90 will have leg lengths of 1 625 and 2 625 respectively.

Sheet metal bend radii. First we must start with the k factor. When we calculate the bend allowance we find that it equals 457. The problem with bending too tightly.

Radii for various thicknesses expressed in terms of thickness t. Per the aluminum association inc. Use an angle finder tool to set the bend radius for your aluminum piece. Simply move the legs into the position that corresponds to the angle you need.

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.
