Copper Machining Services
PRECI5 engineers custom, tight-tolerance components from premium pure coppers and high-conductivity copper alloys. Leveraging advanced CNC milling, turning, and micro-machining capabilities, we solve burr control and work-hardening challenges for demanding thermal and electrical applications.
High Conductivity Alloys
Full support for oxygen-free (C10100/C10200) and electrolytic tough pitch (C11000) grades, preserving peak electrical IACS ratings and thermal transfer limits.
Extreme Burr Management
Optimized chip-breaking toolpaths and polished carbide geometry eliminate gummy edge buildup and micro-burrs across fragile cooling fins and electrical contacts.
Cleanroom & Surface Finishing
Post-processing including ultrasonic degreasing, anti-tarnish passivation, silver plating, and gold electroplating tailored for vacuum and RF hardware.

Copper is valued for its thermal and electrical performance, but its high ductility, high thermal dissipation, and tendency to smear present serious manufacturing challenges. Standard tooling often results in tearing, built-up edges, and tool deflection.
At PRECI5, we deploy specialized high-rake geometry, mirror-polished diamond coatings, and controlled pressurized coolant strategies. Whether working with gummy C10100 for semiconductor vacuum assemblies or high-speed free-cutting C14500 tellurium copper for busbars, we hold tolerances down to ±0.005 mm consistently.
Common Application Sectors
- Semiconductor & Vacuum: High-vacuum chambers, sputtering backplates, and feedthrough terminals requiring ultra-low outgassing OFHC coppers.
- Power & EV Transmission: Heavy-gauge busbars, switchgear terminals, contact pins, and liquid-cooled battery connector blocks.
- RF & Microwave Electronics: Precision-milled waveguides, coaxial resonators, and antenna heatsinks requiring fine micro-features.
- Thermal Management: Direct-contact cold plates, vapor chamber internal pedestals, and skived heat spreaders.
