7075-T651 Aluminum Plate

Our 7075-T651 Aluminum Plate is a heat-treated, stress-relieved alloy known for its outstanding strength, toughness, and fatigue resistance. With zinc as the primary alloying element, 7075-T651 delivers strength comparable to many steels while maintaining a much lower weight — making it ideal for weight-sensitive, high-performance designs.

This alloy is particularly well-suited for aerospace components, defense equipment, and precision-engineered tooling. Its T651 temper means it has been solution heat-treated, stress-relieved by stretching, and artificially aged, ensuring maximum dimensional stability during machining.

We offer precision-cut plates in multiple thicknesses, with strict quality control to guarantee consistency. The 7075-T651 Aluminum Plate is the preferred choice for demanding applications requiring high strength, excellent machinability, and superior fatigue resistance
