Strength-to-weight potential
Supports compact machined structures where aluminum mass and higher mechanical demand must be balanced.
Metal material
Aluminum 7075 Manufacturing and Custom Parts
A high-strength aluminum alloy for loaded structural parts and complex precision components.
- High strength
- Good machinability
- Lightweight
Material overview
Higher strength for lightweight parts with demanding load paths.
Aluminum 7075 is considered for robotic joints, optical mounts, gripper components, and other machined structures where a stronger aluminum alloy may help reduce weight without moving to steel. Its value is greatest when the design controls sharp transitions, clamping distortion, and the relationship between machining and finishing.
A 7075 project review should identify the specified temper, loading direction, fatigue-sensitive features, finish, and inspection points. Kewei uses that information to plan roughing, stress control, finishing passes, and measurement access.
Key properties
Performance characteristics translated into manufacturing decisions.
Precision machining
Suitable for multi-face and 5-axis work when datum strategy and stable workholding are established.
Surface response
Can receive anodic and prepared cosmetic finishes, with color variation reviewed before approval.
Structural use
Often considered for joints, mounts, fixtures, and loaded mechanisms rather than general sheet forming.
Suitable processes
Manufacturing routes for this material.
Compatible Surface Finishes
Surface options reviewed with the base material.
Typical applications
Common Aluminum 7075 part families.
Robotic joints and wrist housings
Automation gripper jaws
Optical mounts
Drone and lightweight frame joints
Loaded fixtures
Complex 5-axis structural parts
Design considerations
Control the features that affect function and process stability.
G 01
Use generous transitions in loaded corners where function allows.
G 02
Provide clear datums for multi-face inspection.
G 03
Flag fatigue-sensitive holes, threads, and contact areas.
G 04
Review finish masking and tolerance allowance before machining.
Limitations
Requirements that need engineering review.
- Corrosion behavior and finish response differ from general-purpose 6061.
- Tight internal corners increase tool access and machining time.
- Thin ribs and asymmetric material removal can release stress.
- Anodizing can show shade variation and may affect fitted dimensions.
RFQ checklist
Material details to include in the quotation package.
Clear requirements help engineering, finishing, inspection, and purchasing review the same target.
- 017075-T6 is a common specification, but the exact temper belongs on the drawing.
- 02Plate, bar, and billet condition should be aligned with stock availability and documentation needs.
- 03Material substitution should never be made without written engineering approval.

FAQ
Aluminum 7075 questions from engineering and sourcing teams.
When is 7075 considered instead of 6061?
It is commonly reviewed when a lightweight component has higher structural demand. The decision should also consider corrosion exposure, finish, stock condition, cost, and the geometry of the load path.
Can complex 7075 parts be machined in five axes?
Yes. Five-axis machining can improve access and reduce setups for compound geometry, but datum strategy, tool reach, and inspection access still need engineering review.
Does black anodizing look identical on every 7075 batch?
No. Alloy condition, surface preparation, geometry, and processing batch can influence shade. Critical cosmetic expectations should be approved with samples or a defined acceptance method.
