When working with aluminum over sheet metal, several variables need to be considered. Aluminum is typically thicker and stronger, and requires more force to bend as well as consideration of edge conditions and punch nose radii.
This free chart outlines what bend radii is required for the approximate thickness of aluminum. We recommend printing it out to keep as a reference.
Minimum permissible radius varies with nature of forming operation, type of forming equipment and design and condition of tools. Minimum working radius for given material or hardest alloy and temper for a given radius can be ascertained only by actual trial under contemplated conditions of fabrication.
