Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
Minimum bend radius aluminum sheet metal.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
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.
5052 h32 aluminum bends in about the same way as mild steel.
Bend radii and minimum bends are limited to certain values or ranges which are determined by the equipment and tooling combinations available to the manufacturer.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
Use this document to choose values that are both manufacturable and meet your needs.
For example 6061 t6 aluminum is very difficult to bend.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
Recommended minimum bend radii for 90 degree cold forming of sheet plate temper 1 64 in.
Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.
When designing sheet metal parts and enclosures it is helpful to use these values as the basis for your design.
This tool allows you to determine tonnage internal radius v die opening and minimum flange you just have to insert the characteristics of the sheet metal to be bent.
It requires an inside bend radius of at least 6x the material thickness.
Per the aluminum association inc.
3003 h14 is extremely ductile.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.
The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.
Bend radii minimum bend sizes.
