2024 Sheet Metal Bend Radius

The bend allowance formula takes into account the geometries of bending and the properties of your metal to determine the bend allowance.

2024 sheet metal bend radius.

Factor 2 thickness and bend radius. Bend radii minimum bend sizes. The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications. Specifing a bend radius from here will help prevent hair line cracks.

3003 0 1100 0 6061 s0 5052 s0. Radii for various thicknesses expressed in terms of thickness t. Table 1 preferred recommended 90 degree bend radii for various sheet metals. We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.

Another factor to consider is that during the process of bending the metal hardens and strengthens by reason of the working effect. It is possible to choose other bends if you require but additional lead time and tooling charges may apply. The table below shows the permitted bend radii for 90 o bending. Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.

The material thickness will be measured in decimal form not by the gauge number. The brake radius bars of a sheet metal brake can be replaced with another brake radius bar with a different diameter. Use this document to choose values that are both manufacturable and meet your needs. The bend radii listed are standard minimum for manufacturing for aerospace and space applications.

You will need to know your material thickness mt the bend angle b the inside radius ir and the k factor k. Figure 2 for example a 0 032 inch 2024 t3 l channel needs to be bent with a radius of 1 8 inch and a radius bar with a 1 8 inch radius must be installed. It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii. The minimum bend radius data shown in these charts is measured to the inside of the bend.

Sheet metal bend radii if these guidelines are not followed more research and or some form of analysis may be requried. 2024 t3 1020 1025 4130 ann. Commercial sheet metal radius are created with less concern for stresses created during forming and radii can approach zero sharp internal corner for many thin sheet metal gages. 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.
