Oxygen Free Copper Round Rod C10100 5mm-200mm Diameter Machining Grade
Oxygen-Free Copper (C10100) Round Rods are engineered for ultra-high-precision applications requiring zero oxygen content and superior electrical/thermal performance. With a purity of 99.99% Cu and oxygen levels ≤0.0005%, these rods meet ASTM B170, EN 13600, and JIS H3510 standards, making them ideal for vacuum systems, semiconductor manufacturing, and aerospace components. Available in 5mm–200mm diameters, they offer unmatched ductility and resistance to hydrogen embrittlement.
Key Advantages:
- Ultra-High Purity: 99.99% copper (C10100) with oxygen ≤0.0005% for critical electronic applications.
- Exceptional Conductivity: 102% IACS conductivity (59 MS/m) and thermal conductivity of 391 W/m·K.
- Precision Machinability: Tight tolerances (±0.02mm for ≤50mm, ±0.05% for >50mm) for CNC/lathe work.
- Hydrogen Embrittlement Resistance: Stable performance in hydrogen-rich environments (e.g., particle accelerators).
- Global Compliance: RoHS, REACH, and NASA-approved for aerospace use.
- Customization: Cut-to-length (10mm–6m), polished/electropolished finishes, and vacuum-sealed packaging.
