Overview
Pearson Manufacturing provides access to specialized cobalt alloy machining solutions, tailored for high-temperature and high-wear applications. Whether manufactured in-house or through our Canadian supplier network, we coordinate every step of production with strict quality control to meet aerospace, medical, and industrial standards.
Our Capabilities
Our capabilities — whether performed at our facility or through a trusted partner — include:
- CNC Milling: contouring & surfacing of complex cobalt geometries
- Turning: precision shafts, sleeves & seals in cobalt alloys
- Drilling & Threading: high-precision holes & threads without chipping
- Surface Grinding: flatness & finish control on wear-critical parts
- Manual Machining: rework & low-volume modifications on tough alloys
- Repair & Finishing: weld prep, surfacing & restoration post-machining
Why Cobalt Alloys?
- Machining of high-temp, wear-resistant alloys with minimal tool wear
- Tight tolerances held even under thermal stress
- Exceptional surface finishes for aerospace & medical standards
- Extended component life in extreme environments
- Expert handling of proprietary cobalt-chrome and Stellite grades

FAQ
What makes cobalt alloys challenging to machine?
Their high hardness and work-hardening tendency require carbide/CBN tools, optimized feeds/speeds, and precise coolant control.
What tolerances can you achieve on cobalt parts?
We routinely hold ±0.005″ (±0.13 mm) or better, depending on geometry and alloy grade.
Can you achieve medical-grade surface finishes?
Yes—we finish cobalt-chrome to Ra 0.4 µm or better, meeting surgical implant standards.
Do you offer post-machining heat treatment or coatings?
We coordinate heat-treating and PVD/CVD coatings through certified partners to enhance wear and corrosion resistance.
Is this manufactured in-house?
Some cobalt alloy projects are machined in-house at our Ontario facility, while others are fulfilled through our trusted Canadian manufacturing partners. Pearson acts as your sourcing and quality coordination partner throughout.
