7xxx Series AA7050 Aluminum Alloy Plate 7050 Aluminium Sheet
As a premium aerospace-grade material, 7050 offers the best strength-toughness combination
among aluminum alloys, though at higher cost. It's primarily specified for critical load-bearing
applications where performance outweighs cost considerations.
Key Properties
Alloy Series: Al-Zn-Mg-Cu (super high-strength aluminum alloy)
Typical Composition
Zn: 5.7-6.7% Mg: 1.9-2.6% Cu: 2.0-2.6%
Mechanical Properties
Tensile strength: ≥510 MPa (T6 temper), up to 570 MPa peak
Yield strength: ≥450 MPa (T74 temper)
Elongation: 8-10% (maintains moderate ductility)
Common Tempers
| Temper | Treatment Process | Characteristics |
| T6 | Solution heat treated + artificially aged | Maximum strength but reduced corrosion resistance |
| T73 | Over-aged | 10% lower strength but improved stress corrosion resistance |
| T7451 | Stress relieved + over-aged | Balanced properties (preferred for aerospace) |
Competitive Advantages
♦ Ultra-high strength: 10-15% stronger than 7075 alloy
♦ Excellent fracture toughness
♦ Good machinability for complex components
Standard Thickness Ranges
Aerospace: 1.5-50 mm (wing skins, spar beams)
Military: 10-100 mm (armor plates, missile housings)
Tooling: 20-200 mm (precision mold bases)
Primary Applications
• Aerospace
Primary aircraft structures (e.g., Boeing 777 wing components)
• Defense
Armored vehicles, naval missile launchers
• Space
Spacecraft components, helicopter rotor hubs
• Industrial
High-end injection mold bases
Company Advantages
We use the Wolrd Advanced Equipments for your Aluminium Alloy Material
• All the melting and holding furnaces are supplied by GAUTSCHI (Switzerland) Company.
they improve the quality of Aluminum alloy slab which can guarantee Aluminium alloy
products with high-performance.
• 1+1+4 hot rolling mills (1 Reversible Roughing Mill +1 Finishing Mill + 4 Tandem Finishing Mills)
We import these equipments from SMS Group (Germany). All the hot finishing rolling mills
adopt the CVC flatness control technology, which can produce hot-rolledcoils and sheets with
ideal flatness.
