Aluminum Sheet Metal Bend Radius

If a piece of material is bent too tightly problems can occur.

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. Simply move the legs into the position that corresponds to the angle you need. The problem with bending too tightly. The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.

On each leg you ll see a series of markings indicating various angles in relation to the opposing leg. The bending angle is 90 sheet thickness 5 mm and the inside radius is 6 mm. Preferred recommended 90 degree bend radii for various sheet metals. Grain direction is formed in metal in the direction in which the sheet was rolled at the steel mill.

Sheet metal bend radii. Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii. The most common problem with bending a piece of sheet metal too tightly is. Radii for various thicknesses expressed in terms of thickness t.

When we calculate the bend allowance we find that it equals 457. Most angle finders feature two short legs that rotate independently of one another. Still if you want to avoid cracking abide by the minimum bend radius in 0 25 in thick 6061 t6 which is quite large see figure 3 and avoid bending acute angles. 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 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. First we must start with the k factor. We want to know the final length of the detail. Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.

Say you get a print that says you need to bend a part to an external angle of 100 degrees that s an internal angle of just 80 degrees. Use an angle finder tool to set the bend radius for your aluminum piece. 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. Per the aluminum association inc.

If these guidelines are not followed more research and or some form of analysis may be requried.
