Yes, Aluminum 7050 generally offers better stress-corrosion resistance and improved toughness compared to 7075, especially in thicker sections. While both alloys provide excellent strength, 7050 is more stable under heavy loads and severe environments, which is why aerospace structures often prefer 7050 for critical components. 

Welding Aluminum 7050 is not recommended because its high zinc and copper content makes it highly susceptible to cracking during the welding process. Even if welds are completed, the heat-affected zone loses significant mechanical strength. For assemblies that require joining, mechanical fasteners or precision machining of a single-piece structure is preferred. 

The most widely used tempers for Aluminum 7050 are T7451 and T7651. These tempers offer excellent resistance to stress corrosion cracking, improved fatigue performance, and stable mechanical properties. They are commonly selected for aerospace bulkheads, wing skins, landing gear structural parts, and heavy-load components. 

Yes, Aluminum 7050 can be anodized, especially through Type II and Type III (hard anodizing) processes. Because the alloy contains higher copper and zinc levels, pre-cleaning and specialized preparation are required. When done correctly, the anodized surface provides excellent wear resistance and corrosion protection. 

Aerospace, defense, motorsports, and high-performance engineering rely heavily on Aluminum 7050 due to its exceptional strength-to-weight ratio, fatigue resistance, and structural stability. It is commonly used in wing spars, aircraft frames, landing gear components, missile structures, and racing suspension systems.
