Aluminum Rectangle Bar 2024-T3511 Extruded is a high-strength structural alloy widely recognized for its excellent toughness and high resistance to fatigue. The T3511 temper indicates the material has been solution heat-treated, stress-relieved by stretching, and specifically straightened to ensure minimal distortion during complex machining. Unlike cold-finished bars, the extruded finish provides a cost-effective solution for structural applications where extreme surface precision is less critical than internal strength. This alloy is a staple in the aerospace industry, frequently used for wing and fuselage structures due to its ability to withstand high tension and cyclic loading. While it offers superior mechanical properties, it is generally recommended to use a protective coating or cladding to prevent corrosion in high-moisture environments.
