C10200 oxygen-free copper is a high-purity copper alloy that complies with ASTM B152/B152M standards. Its oxygen content is extremely low (≤0.001%), and the contents of other impurities (such as phosphorus and sulfur) are strictly controlled, resulting in a purity exceeding 99.95%. Due to its excellent electrical and thermal conductivity, ductility, and corrosion resistance, it is widely used in applications requiring stringent material properties.
Key Features of ASTM B111 C10200 Alloy Copper Tubing
High electrical and thermal conductivity
Electrical conductivity ≥101% IACS (International Annealed Copper Standard), making it an ideal material for power transmission and electronic components.
Excellent thermal conductivity makes it suitable for heat dissipation components and applications requiring high heat transfer.
Extremely low oxygen content
Oxygen-free copper is not susceptible to hydrogen embrittlement at high temperatures or in reducing atmospheres, making it suitable for vacuum or protective environment applications.
Excellent Processing Properties
High ductility allows for hot and cold processing, resulting in complex shapes such as wire, sheet, and tube.
Annealed tensile strength is approximately 200-250 MPa, with an elongation ≥35%. Hard tensile strength can reach 300-400 MPa.
Corrosion Resistance
Excellent oxidation resistance in dry, pollution-free environments, ensuring high long-term stability.
Main Applications of C10200 Oxygen-Free Copper
Electronics and Electrical Industries
High-end wires, cables, connectors, transformer windings, etc., ensuring efficient power transmission.
Semiconductor lead frames and vacuum tube components rely on its high purity and low outgassing properties.
Vacuum Devices and Aerospace
Vacuum tubes, particle accelerator chambers, and spacecraft sealing components prevent performance degradation caused by oxidation.
High-Temperature Applications
High-Temperature Furnace Linings and Induction Heating Coils, withstanding extreme temperatures while maintaining stable conductivity.
Precision Instrument Manufacturing
Waveguides, superconducting magnet support structures, and laser components meet high-precision and low-loss requirements.
