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.
