Premium 7075 Aluminum Plate: The Ultimate High-Strength Aerospace Alloy
7075 aluminum plate is one of the strongest aluminum alloys available, making it a cornerstone for high-stress applications in the aerospace and defense industries. As a 7xxx series alloy with zinc as the primary alloying element, it offers excellent mechanical properties, high toughness, and resistance to fatigue.
Our 7075 aluminum sheets are primarily available in T6 and T651 tempers, ensuring exceptional structural integrity and stability during machining.

Key Advantages
- Ultra-High Strength: Offers tensile strength comparable to many types of steel while remaining lightweight.
- Excellent Fatigue Resistance: Designed to withstand repeated stress cycles, perfect for structural components.
- Superior Machinability: Despite its hardness, 7075-T651 provides good machining characteristics for complex parts.
- High Strength-to-Weight Ratio: Ideal for industries where reducing weight is critical for performance and fuel efficiency.
Drawbacks
- Corrosion Resistance: Lower resistance compared to 5xxx or 6xxx series (often requires anodizing or cladding).
- Weldability: Generally difficult to weld; mechanical fastening or specialized techniques are recommended.
- Cost: Higher price point than standard alloys like 6061 due to its complex composition and strength.
Common Applications
7075 aluminum plate is the "gold standard" for demanding environments:
- Aerospace: Aircraft structures, wing skins, and fuselage components.
- Defense: Missile parts, military vehicles, and high-pressure gears.
- Tooling & Molding: Precision plastic injection molds and high-stress tool jigs.
- High-End Sports Gear: Professional bicycle frames, climbing equipment, and archery bows.
Packaging & Delivery
We ensure every 7075 aluminum plate reaches you in perfect condition:
