The minimum bend radius data shown in these charts is measured to the inside of the bend.
Aluminum sheet metal bend radius chart.
Where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
Example flat size 2 2 095 3 905 bend radius 22 ga.
We go beyond the general rules of sheet metal bending as our customers want tight bend radii for sheet metal parts.
If these guidelines are not followed more research and or some form of analysis may be requried.
Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.
Material bend radii and minimum bend size charts please note.
Use the minimum bend dimension values in the charts below for your minimum closeness of cutout to a bend.
Steel american iron and steel institute.
This free chart outlines what bend radii is required for the approximate thickness of aluminum.
Bend allowance mild sheet steel 90 degree bend allowance.
We recommend printing it out to keep as a reference.
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 radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Preferred recommended 90 degree bend radii for various sheet metals.
Refer to table s for your choice of material.
When working with aluminum over sheet metal several variables need to be considered.
032 18 ga 040 16 ga.
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.
