7249 aluminum is a zinc-aluminum-magnesium-copper alloy used primarily in high-strength aerospace applications requiring superior fracture toughness and stress-corrosion-cracking (SCC) resistance compared to 7075. The T6151 temper (solution heat-treated, artificially aged, and stress-relieved) provides yield strengths in the 435–480 MPa range with improved toughness and dimensional stability, particularly suited for critical fuselage and structural components where both strength and damage tolerance are essential.
