Product Description
7075 T6 Aerospace Grade Aluminum Sheet 3.0mm Zinc Magnesium Copper Alloy High Strength for Aircraft Wing Components
Ultra-High Strength at One-Third the Weight of Steel
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.
Key Features
- 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
Applications
- 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
Quality Assurance
Comprehensive Testing & Certification
Every sheet undergoes electrical conductivity testing (32-36% IACS for T6 verification), ultrasonic C-scan inspection for internal integrity per AMS-STD-2154 Class A, chemical analysis by OES, tensile testing per ASTM E8, and hardness testing. AMS 4045 aerospace specification compliance with full melt-to-product traceability. NADCAP-accredited testing laboratory certification available.
