7075 T6 Aerospace Grade Aluminum Sheet 3.0mm Zinc Magnesium Copper Alloy High Strength for Aircraft Wing Components

Our 7075 T6 Aerospace Grade Aluminum Sheet is the highest strength aluminum alloy commercially available, with tensile strength exceeding 540 MPa — approaching that of structural steel at only one-third the weight. Engineered with a zinc-magnesium-copper alloy system and fully heat treated to T6 temper, this 3.0mm sheet is the definitive choice for aircraft structural components, wing spars, fuselage frames, and high-stress aerospace applications where failure is not an option.

• Ultra-High Strength: ≥540 MPa tensile strength and ≥470 MPa yield strength, comparable to mild structural steel (S235) but at only 34% of the weight
• Zinc-Magnesium-Copper Alloy: 5.1-6.1% Zn, 2.1-2.9% Mg, and 1.2-2.0% Cu provides precipitation hardening capability for maximum mechanical properties
• Full T6 Heat Treatment: Solution treated at 480°C, water quenched, and artificially aged at 120°C for 24 hours for peak strength and hardness
• Excellent Fatigue Properties: Superior fatigue crack growth resistance critical for cyclic loading in aerospace structures
• Outstanding Strength Retention: Maintains significant strength at moderately elevated temperatures up to 120°C continuous service

• Aircraft wing spars and ribs
• Fuselage frames
• Missile components
• High-performance bicycle frames
• Rock climbing equipment
• Competition firearms receivers
• Molds for plastic injection
• Precision structural components where weight reduction is critical
