Product information

Model: 7022
Availability: Customizable 
7022 aluminum alloy is a high-strength deformation aluminum alloy with excellent mechanical and processing properties. Its main characteristics and applications are as follows:
‌Mechanical properties‌
‌Tensile strength: ≥ 460 MPa (in the state of solution treatment + artificial aging T6)‌
‌Yield strength: ≥ 380 MPa‌
‌Post-fracture elongation: ≥ 8% (A gauge length)‌
‌Hardness: 133 HBW‌
‌Corrosion resistance and high-temperature resistance‌
The addition of zirconium (Zr) and chromium (Cr) enhances the alloy's heat resistance and strength‌
Suitable for structural components in high-temperature environments‌
Application fields
‌Aerospace equipment: used for high-strength components of aircraft structures and spacecraft shells‌
‌Construction and transportation: doors and windows, vehicle components, motorcycle frames, etc‌
‌Consumer industrial products: precision components that need to withstand pressure processing‌
Processing techniques
‌Solution treatment: optimize performance through specific processes (such as holding at 466°C and then water quenching)‌
‌Aging strengthening: T6 artificial aging (holding at 120°C for 24 hours) further increases strength‌
This alloy is widely used in industrial fields with high requirements for strength and heat resistance due to its excellent comprehensive performance.

Chemical composition 
The chemical composition of 7022 aluminum alloy is as follows (main components and content ranges):
Aluminum (Al): 100%
Silicon (Si): ≤ 0.50%
Iron (Fe): ≤ 0.50%
Copper (Cu): 0.50 - 1.0%
Manganese (Mn): 0.10 - 0.40%
Magnesium (Mg): 2.6 - 3.7%
Chromium (Cr): 0.10 - 0.30%
Zinc (Zn): 4.3 - 5.2%
Titanium + Zirconium (Ti + Zr): ≤ 0.20%
Other unspecified elements: each ≤ 0.05%, total ≤ 0.15%
</noteList> This alloy is based on aluminum and its properties are enhanced by adding elements such as manganese and zirconium. It has high strength, corrosion resistance and high-temperature resistance, and is commonly used in the manufacturing of aerospace structural components. The chemical composition may vary slightly depending on different standards (such as the American Aluminum Association AA 7022).
