Frequently Asked Questions

Common engineering questions regarding tolerances, material traceability, and turnaround for Aluminum 7075-T6 Aerospace High-Strength Machining.

How does 7075-T6 compare to 6061-T6? +
7075-T6 is roughly 80% stronger than 6061-T6, offering strength comparable to mild structural steel at one-third the weight, though it is less corrosion-resistant in saltwater.
Is 7075-T6 weldable? +
Traditional fusion welding of 7075 causes severe micro-cracking and strength loss. Components are joined with precision mechanical fasteners or friction stir welding (FSW).
Does 7075 anodize as bright as 6061? +
Because 7075 contains 1.6% copper, anodized colors appear slightly more bronze or olive-toned compared to 6061. Hardcoat anodizing gives a deep charcoal or olive-grey finish.
Can you provide AS9102 First Article Inspection reports for 7075 parts? +
Yes. Complete AS9102 Form 1, 2, and 3 documentation with ballooned engineering drawings and CMM metrology data is available.
