Aluminum Rectangle Bar 7075-T6511 Extruded is a premier, ultra-high-strength alloy designed for the most demanding structural applications in aerospace, defense, and high-performance engineering. The T6511 temper indicates that the material has been solution heat-treated and artificially aged for peak hardness, then stress-relieved by stretching and minor straightening to ensure excellent stability during machining. As an extruded product, this rectangular bar offers a cost-effective way to source high-strength material for large-scale structural frames, mounting blocks, and specialized tooling. Zinc is the primary alloying element, giving this metal a strength-to-weight ratio that rivals many steel alloys while remaining significantly lighter. While it is incredibly tough, it is generally recommended for use with protective coatings or anodizing to maintain its integrity in corrosive environments.
