What is the acceptable radius for a 90-degree bend in 0.064-inch thick aluminum alloy 2024-T3?

The acceptable radius for a 90-degree bend in 0.064-inch thick aluminum alloy 2024-T3 is 3 to 5 times the sheet thickness. This is based on metalworking practices that ensure material integrity and performance after bending.

When bending aluminum, particularly alloys like 2024-T3, it's critical to consider the radius to avoid defects such as cracking or undesirable strain. A radius that is 3 to 5 times the thickness allows for sufficient material flow, maintaining the strength and fatigue resistance of the aluminum while minimizing the risk of fracture.

In the case of 2024-T3 aluminum, this range strikes a balance between processing ease and the mechanical properties needed for structural applications. Therefore, adherence to these guidelines is central to effective practices within the aerospace industry, where this material is commonly used.
