Better stress corrosion resistance
Improved thick-section performance
Superior fracture toughness
Enhanced fatigue resistance
Better structural stability under high-load environments
Because of these advantages, 7050 T7451 aluminum plate is widely used in:
Aircraft wing structures
Aerospace bulkheads
Fuselage frames
Military structural components
Precision CNC aerospace machining
Xi'an Dongmeng Group Co., Ltd specializes in manufacturing export-grade 7050 aerospace aluminum alloy products with strict dimensional tolerances, full traceability, and international standard compliance.
Why Choose 7050 Aluminum?
1. Excellent Performance in Thick Sections
One of the key advantages of 7050 aluminum is its ability to maintain high mechanical properties in relatively thick sections.
This makes 7050 particularly attractive for:
Heavy aerospace plate
Aircraft bulkheads
Fuselage frames
Wing structural components
Large CNC-machined aerospace parts
High-load structural fittings
7050 has historically been used especially where thick plate performance and short-transverse properties are important.
2. High Fracture Toughness
Compared with conventional high-strength aluminum alloys, 7050 provides a strong balance between tensile strength and fracture toughness.
This is particularly important for structural components exposed to cyclic loading, fatigue and crack-propagation risks.
3. Improved Stress-Corrosion Resistance
Properly selected over-aged tempers such as T7451 are designed to provide strong resistance to stress-corrosion cracking while maintaining high structural strength.
For long-service-life aerospace structures, this balance can be more important than simply selecting the alloy with the highest possible tensile strength.
4. Good Machining Stability
7050 plate is widely used for high-value CNC components because it offers:
Good machinability
Stable performance after heat treatment
Good dimensional stability
Suitability for deep-pocket machining
Good surface finish
High strength-to-weight ratio

FAQ
1. What is 7050 aluminum alloy?
7050 aluminum is a high-strength Al-Zn-Mg-Cu-Zr alloy widely used for aerospace and other high-load structural applications. It offers a strong combination of tensile strength, fracture toughness and resistance to stress-corrosion cracking. The nominal composition includes approximately 5.7–6.7% Zn, 1.9–2.6% Mg and 2.0–2.6% Cu.
2. What are the common tempers of 7050 aluminum?
Common tempers include 7050-T7451, 7050-T7651, T74510 and T74511, depending on the product form and required mechanical properties. T7451 is commonly selected where fracture toughness and stress-corrosion resistance are important, while T7651 can provide somewhat higher strength.
3. What is the difference between 7050-T7451 and 7050-T7651?
7050-T7451 generally emphasizes a balance of toughness, dimensional stability and stress-corrosion resistance. 7050-T7651 normally provides higher tensile and yield strength. Typical published values for T7451 are about 524 MPa tensile strength and 469 MPa yield strength, while T7651 can reach approximately 552 MPa tensile strength and 490 MPa yield strength. Actual guaranteed values depend on thickness and specification.
4. What is the difference between 7050 and 7075 aluminum?
Both are high-strength 7000-series aluminum alloys, but 7050 is especially favored for thick aerospace sections requiring improved fracture toughness and stress-corrosion performance. 7075 is more widely used in general high-strength applications and is available in a broader range of commercial forms.
5. Is 7050 aluminum suitable for thick plates?
Yes. One of the major advantages of 7050 is its suitability for medium and heavy plate sections, where maintaining strength, toughness and corrosion resistance through the thickness is important. This is one reason it is commonly used for aircraft structural components.
6. What are the typical applications of 7050 aluminum?
Typical applications include aircraft wing structures, fuselage frames, bulkheads, structural plates, landing-gear-related components, high-load machined parts, tooling and other applications requiring high strength and good fracture toughness.
7. Can 7050 aluminum be machined?
Yes. 7050 aluminum has good machinability in heat-treated conditions and is suitable for CNC milling, drilling, turning and precision machining. For high-precision parts, customers should specify flatness, dimensional tolerance, machining allowance and final temper requirements when ordering.
8. Is 7050 aluminum suitable for welding?
7050 is generally not preferred for conventional fusion-welded structural fabrication because welding can significantly affect the properties of the heat-affected zone. Mechanical fastening, bolting or specially qualified joining methods are normally preferred for critical structural applications.
9. Does 7050 aluminum have good corrosion resistance?
Yes. Properly over-aged tempers such as T7451 are designed to provide improved resistance to stress-corrosion cracking while maintaining high mechanical strength. For aggressive service environments, anodizing, conversion coating or other protective surface treatments may also be specified.
10. What is the density of 7050 aluminum?
The typical density of 7050 aluminum is approximately 2.83 g/cm³, which allows it to provide a high strength-to-weight ratio for aerospace and transportation structures.
11. What product forms of 7050 aluminum can be supplied?
7050 is commonly supplied as plate, sheet, forged or extruded products, depending on the applicable specification and required temper. For B2B purchasing, plate and machined blanks are among the most common forms.
12. What information should I provide when requesting a quotation for 7050 aluminum?
Please provide the required alloy, temper, product form, thickness, width, length, quantity, applicable standard, tolerance, surface requirement and inspection requirement. If the material will be used for aerospace or precision machining, also specify any required MTC, ultrasonic testing, dimensional inspection or third-party inspection.
13. Can 7050 aluminum be supplied with material certificates?
Yes. Material test certificates can be supplied according to the agreed specification and purchase requirements. Chemical composition, mechanical properties, heat number and dimensional information can be included where applicable.
14. Can 7050 aluminum plate be cut to custom sizes?
Yes. 7050 plate can be supplied as full-size plate or processed into custom blanks through sawing, cutting and CNC machining. Custom dimensions can help reduce customer machining time and material waste.
15. Is 7050 aluminum better than 7075?
Not in every application. 7050 is often the better choice for thick, highly stressed aerospace structures where fracture toughness and stress-corrosion resistance are critical, while 7075 may be more economical and more readily available for general high-strength structural parts. The correct selection depends on thickness, temper, environment and design requirements.
