High strength without steel-level mass.
7075-T6 is selected for highly loaded structural parts, precision fixtures and performance components. It machines cleanly, but corrosion, stress concentration, stock condition and finishing require more deliberate engineering than 6061.
- 01Aerospace brackets and structural fittings
- 01Robotic arms and lightweight mechanisms
- 01High-load jigs, fixtures and tooling
- 01Hard anodized wear components
Design for strength and environmental reality.
The alloy is not normally fusion welded and is more sensitive to corrosion than 6061. Avoid sharp internal corners in fatigue-loaded parts and confirm temper, grain direction and protective finish for critical applications.
- 02Use generous radii at load transitions
- 02Call out temper and applicable material specification
- 02Review stress-corrosion exposure
- 02Plan anodize buildup on fits and threads

Can 7075 aluminum be welded?+
Conventional fusion welding is generally not recommended because cracking and degraded properties are common. Mechanical fastening or redesign is usually preferred.
When should I choose 7075 over 6061?+
Choose 7075 when significantly higher strength and fatigue performance justify its higher cost and reduced weldability and corrosion resistance.
