Material expertise
2017 aluminum machining with process control built in
2017 aluminum is valued for its high strength-to-weight ratio and excellent machinability. It is a practical choice for structural components, rivets, and high-stress mechanical parts that require efficient material removal and accurate features.
Compared with 6061 and 7075, 2017 requires focused attention to corrosion protection and internal stress. Our engineers account for these material characteristics when planning machining, finishing, and inspection.
Machining performance
Strong chip-breaking and surface-finish performance support tight-tolerance features and efficient CNC machining.
Surface protection
2017 is more susceptible to corrosion than 6061, so hard anodizing or chromate conversion may be specified to limit oxidation.
Stress management
Machining plans account for internal stress to help prevent warping in thin-walled or complex housings.
Production scope
Aluminum machining capabilities
Our facility supports 3-axis, 4-axis, and 5-axis milling alongside CNC turning and turn-mill work. A dedicated aluminum-only workflow keeps cutting parameters, workholding, and quality controls aligned with aluminum thermal expansion rates.

Process discipline
Precision manufacturing for complex parts
By limiting our scope to aluminum, our CNC programmers and inspection team can focus on the specific challenges of aluminum component manufacturing.
Deformation control
Preventing distortion in thin-walled enclosures and plates during machining.
Thermal management
Managing heat build-up to maintain tight tolerances down to ±0.01 mm.
Cosmetic integrity
Handling components carefully to meet finish requirements for optical and consumer-facing equipment.
Internal pockets
Removing material efficiently from large housings while maintaining stability and flatness.
Aluminum-only advantage
A workflow dedicated to your material
Many machine shops treat aluminum as a secondary material alongside steel and stainless steel. Our focused approach avoids compromised cutting speeds, unsuitable tooling choices, and potential cross-contamination.
- Stable processes. Machines stay calibrated for aluminum without changing setups for different material hardnesses.
- Expert finishing. Finishing choices account for the nuances of different aluminum grades and environmental requirements.
- Engineering communication. We understand the design trade-offs between grades such as 2017 and 7075.

Common questions about 2017 aluminum
Why is 2017 aluminum suitable for mechanical parts? +
2017 combines a high strength-to-weight ratio with excellent machinability, making it suitable for structural components, rivets, and high-stress mechanical parts.
Does 2017 aluminum need surface protection? +
Yes. It is more susceptible to corrosion than 6061, so appropriate finishing such as hard anodizing or chromate conversion should be considered where oxidation resistance and long-term performance matter.
What files are needed for an accurate quote? +
Please provide 3D models in STEP or STP format and 2D technical drawings in PDF format, including defined tolerances and surface finish requirements.
