Aluminum 6061‑T6 VS 7075‑T3 for CNC machined parts
Compare Aluminum 6061‑T6 and 7075‑T3, two most popular CNC machining aluminum alloy. Learn strength, cost and application scenarios.

Aluminum 6061‑T6 vs 7075-T6:
Choose Right Aluminum for Your CNC Parts Aluminum is widely used in custom CNC machined components. 6061‑T6 and 7075 are the two most common grades.
Aluminum 6061‑T6
‑ Good general‑purpose aluminum alloy
‑ Excellent anodizing performance, nice surface appearance ‑ Easy for CNC turning & milling
‑ Lower material cost
‑ Typical use: automation parts, brackets, housings, general mechanical components.
Aluminum 7075‑T6
‑ Much higher mechanical strength
‑ Similar strength to some steel
‑ Slightly higher material cost
‑ Anodizing result is darker than 6061‑T6
‑ Typical use: aerospace accessories, high‑load structural parts, high‑strength fixture
Quick selection guide
‑ For brackets, housings, ordinary equipment parts → 6061‑T6 (recommended for most projects)
‑ For high‑load, high‑strength structural components → 7075‑T6
