Aluminum Alloys AL7075 / 7050 / 7451

Aluminum Alloys 7075, 7050, and 7451 are part of the 7000 series zinc-based aluminum alloys, renowned for their exceptional strength, toughness, and fatigue resistance. These aluminum zinc magnesium copper alloy are specifically engineered for aerospace, military, and high-performance structural applications where reliability under extreme stress is critical.

• AL7075 is among the strongest aluminum alloys, offering an excellent balance of strength-to-weight ratio and machinability, making it a top choice for aerospace and defense parts.
• AL7050 provides superior fracture toughness and stress corrosion resistance, making it ideal for thick-section aerospace components.
• AL7451 is valued for its high strength and dimensional stability, especially in plate products used in aircraft structures.

While corrosion resistance is moderate, these alloys typically undergo surface treatments such as anodizing, cladding, or coating to enhance durability. At GD Prototyping, we deliver premium 7075, 7050, and 7451 alloys tailored for industries demanding lightweight strength, fatigue resistance, and performance reliability.
