Potential application fit
- The design needs a higher strength-to-weight ratio
- A rigid robot, drone or reducer interface is weight-sensitive
- The buyer has already validated the alloy for the service environment

Higher-strength lightweight aluminum
Aluminum 7075 for CNC-machined structural parts.
A higher-strength aluminum option for weight-sensitive robot, drone, reducer and motion-system interfaces when the released design requires more mechanical performance than a general-purpose alloy.
DIRECT ANSWER
How WEKO reviews aluminum 7075.
WEKO reviews Aluminum 7075 for lightweight high-load structural components such as reducer interfaces, motor supports, hubs and rigid brackets. Temper, stress state, corrosion strategy, finish and inspection requirements must be stated on the controlled drawing.
Release details
- 7075 temper and governing material standard
- Load path, wall sections and stress-sensitive transitions
- Finish, corrosion protection and masking requirements
- Material evidence and approved substitution rules
ENGINEERING NOTES
Three controls before manufacturing.
Strength is not the only decision
Corrosion behavior, notch sensitivity, finish and service environment remain part of material selection.
Geometry matters
Sharp transitions, deep pockets and thin walls should be reviewed against workholding and residual-stress risk.
Documentation
Temper, raw-material source and certificate expectations should be defined before quotation.
PROCESS MATCH
Routes reviewed for this material.
Geometry, quantity, quality scope and material availability determine the final route.

MATERIAL FAQ
Questions to settle before release.
Is 7075 always better than 6061?+
No. It offers different strength, corrosion, finishing and cost tradeoffs. Selection belongs to the customer’s engineering requirements.
Can 7075 parts be anodized?+
A specified anodizing route can be reviewed, but alloy response, color expectations, masking and corrosion strategy must be agreed.
Can WEKO support prototypes and repeat batches?+
Yes, subject to drawing review, material availability, capacity, inspection scope and commercial agreement.
