7050 Aluminum Plate: The Ultimate Solution for High-Strength Aerospace Applications
Product Description
7050 aluminum plate is a heat-treatable alloy known for its exceptional combination of high strength, high fatigue resistance, and resistance to stress corrosion cracking (SCC). As an upgraded version of the 7075 alloy, 7050 aluminum exhibits better toughness and corrosion resistance, especially in thick sections.
It is most commonly supplied in the T7451 temper (formerly T73651), which provides an optimal balance between strength and fracture toughness. This makes it the premier choice for structural components in the aerospace and defense industries.

Key Advantages of 7050 Aluminum Plate
- Superior Stress Corrosion Resistance: Optimized for thick plate applications where 7075 might be prone to cracking.
- High Fracture Toughness: Maintains structural integrity under extreme stress and pressure.
- Excellent Machinability: Can be precisely machined into complex shapes for aircraft structures.
- High Fatigue Strength: Extends the service life of critical components subjected to cyclic loading.
- Quench Sensitivity: Lower quench sensitivity compared to 7075, allowing for uniform properties in thicker sections.
Common Applications
7050 aluminum is the industry standard for high-stress structural parts:
- Aerospace: Fuselage frames, wing skins, bulkheads, and ribs for commercial and military aircraft.
- Defense: Missile components and heavy-duty military vehicle structures.
- Tooling: High-end mold manufacturing requiring dimensional stability.
- High-Speed Rail: Structural components requiring light weight and high durability.
Limitations (Disadvantages)
- Weldability: Generally considered non-weldable by traditional fusion methods (requires specialized techniques like friction stir welding).
- Cost: Higher production and alloying costs compared to 6061 or 7075 alloys.
- Anisotropy: Mechanical properties can vary depending on the grain direction (longitudinal vs. transverse).
