FAQ
Q1: What is the difference between 7050-T6 and 7050-T7451?
A1: T6 provides maximum strength but slightly lower stress corrosion resistance, while T7451 offers improved corrosion resistance with slightly reduced strength.
Q2: Can 7050 aluminum sheet be welded?
A2: Welding is possible but not recommended for high-strength applications due to potential loss of mechanical properties. Mechanical fastening or adhesive bonding is preferred.
Q3: What is the typical lead time for 7050 aluminum sheet?
A3: Standard sizes are usually shipped within 2–4 weeks; custom sizes may take 4–6 weeks.
Q4: Do you provide cutting or machining services?
A4: Yes, we can provide CNC cutting, shearing, and machining according to your specifications.
Q5: Can 7050 aluminum sheet be anodized or painted?
A5: Yes, it can undergo anodizing, painting, or other surface treatments for enhanced corrosion resistance and aesthetics.
