Engineered for extreme conditions
Specialized tooling geometries, optimized feed rates, and high-pressure coolant systems help mitigate heat buildup and work hardening.
Nickel Alloy Material Capabilities
Selecting the right nickel alloy means balancing temperature, corrosion, strength, service environment, and machinability. Our team supports a broad range of nickel-based superalloys for prototypes through production batches.
Why nickel alloys require specialized machining
- High work-hardening rates can accelerate tool wear and affect repeatability.
- Low thermal conductivity concentrates heat at the cutting zone.
- Rigid setups and specific carbide tooling help protect surface integrity.
| Material | Primary benefit | Typical application | Machinability |
|---|---|---|---|
| Inconel 625 | High corrosion and oxidation resistance | Chemical processing, marine | Moderate |
| Inconel 718 | High-temperature strength up to 700°C | Aerospace, gas turbines | Difficult |
| Hastelloy C276 | Excellent chemical resistance | Scrubbers, reactor vessels | Difficult |
| Monel 400 | High strength and seawater resistance | Marine, oil and gas | Moderate |
| Incoloy 825 | Acid and alkali resistance | Pollution control, chemical | Moderate |
Machinability is relative to standard stainless steels; all nickel alloys require rigid setups and specific carbide tooling.
CNC Manufacturing Capabilities
PartsMake supports production from single prototypes to large-scale batches. We tailor machining strategies to the alloy’s hardness, thermal behavior, and geometric complexity.
5-Axis Milling
Complex geometryEnables complex geometries such as impellers and turbine blades in a single setup, reducing handling and minimizing deformation risk.
