For example 6061 t6 aluminum is very difficult to bend.
Minimum bend radius aluminum sheet metal.
The tool can calculate the required bending force for bending aluminum stainless steel mild steel and weldox or strenx high strength steels.
Discover all our calculation tools in the calculators section of the top menu.
Aluminum minimum bend radii for 90 degree cold forming of sheet and plate.
Brittle metal such as aluminum generally requires a larger bend radius than ductile material like cold rolled steel.
Bend radii minimum bend sizes.
Steel american iron and steel institute 1 see aisi s fabrication guidlines for cold bending thk 6061 t6.
Aluminum where necessary 5052 h32 may be bent to 1t and 6061 t6 to 1 1 2t.
Use this document to choose values that are both manufacturable and meet your needs.
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.
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.
When designing sheet metal parts and enclosures it is helpful to use these values as the basis for your design.
3003 h14 is extremely ductile.
Aluminum is typically thicker and stronger and requires more force to bend as well as consideration of edge conditions and punch nose radii.
Bend radii minimum bend sizes.
It requires an inside bend radius of at least 6x the material thickness.
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.
Radii for various thicknesses expressed in terms of thickness t.
The minimum bend radius data shown in these charts is measured to the inside of the bend.
5052 h32 aluminum bends in about the same way as mild steel.
The minimum bend radius for aluminum when working with aluminum over sheet metal several variables need to be considered.
It is most economical to use a single bend radius throughout the design but if necessary you can utilize multiple radii.
The bend radii listed are standard minimum if manufacturing for aircraft and aerospace applications.
