The most commonly used grades include C11000 (pure copper) for high electrical/thermal conductivity, C17200 (beryllium copper) for high strength, and C10100 (OFHC copper) for oxygen-free, high-purity applications.

Pure copper is soft and tends to stick to cutting tools, but with optimized tooling and parameters, CMS achieves clean cuts, accurate dimensions, and smooth surface finishes.

We typically achieve ±0.01–0.02 mm, and tighter tolerances may be possible depending on geometry and material condition.

Yes. Common finishes include nickel plating, gold plating, tin plating, as well as polishing, passivation, and anti-oxidation coatings.

Copper offers excellent electrical and thermal conductivity, making it ideal for connectors, terminals, busbars, cooling plates, and RF/microwave parts.

Yes. With 60+ CNC machines, CMS handles prototypes and high-volume production with stable and repeatable quality.

Electronics, automotive (EV), telecommunications, aerospace, medical devices, and high-frequency/thermal applications.
