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

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

• 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.
