Using minimum bend radius, which material would require the most for a 90-degree bend?

The answer indicates that the material requiring the largest minimum bend radius for a 90-degree bend is 7075-T6 at 0.032 thickness. This is primarily due to the characteristics of the material itself, notably its mechanical properties.

7075-T6 aluminum alloy is known for its high strength and low ductility. When bending any material, particularly high-strength alloys like 7075-T6, a larger bend radius is often necessary to prevent cracking or failure at the bend. The minimum bend radius is influenced by the material's thickness and its properties, including ductility, yield strength, and hardness.

In this case, while materials like 6061-T6 and 5052-H32 are also aluminum alloys, they tend to have better ductility compared to 7075-T6, allowing for tighter bend radii without the risk of damage. The thickness of the materials further influences this, as thinner materials generally can handle tighter bends; however, 7075-T6's high strength compels a larger radius despite its relatively thin thickness.

When comparing this option to the others, each has its optimal bend characteristics based on their specific grade and temper, but none would require a larger radius than the 7075-T6 under the
