Best High purity oxygen-free copper Exporters, Companies

Oxygen-free Copper (oxygen-free Copper, OFC) through vacuum melting + carbon reduction process, Oxygen content ≤0.001% (10 ppm), purity up to 99.99%, completely eliminate the interference of copper oxide (Cu₂O) on conductivity. Its electrical conductivity is ≥101% IACS, which is significantly improved compared with ordinary copper (100% IACS), and can reduce high-frequency signal transmission loss, which is suitable for 5G communication base stations, satellite RF components and other scenarios.

Frequently Asked Questions (FAQ)

Q:What is C10100 oxygen-free copper target?

It is a high-purity copper material with extremely low oxygen content, designed to ensure uniform deposition and improve metallization yield during semiconductor chip manufacturing.

Q:Why is hydrogen brittleness resistance important?

Because it prevents the copper from reacting with hydrogen to form destructive bubbles, making the material highly stable and suitable for vacuum tubes and particle accelerators.

Q:How does high temperature resistance benefit target coating?

The material poses no grain boundary oxidation risk below 400℃, making it ideal for the extreme high-temperature environments of semiconductor sputtering coatings.

Q:Can this copper be used in flexible circuit board (FPC) substrates?

Yes. Thanks to its super ductility and elongation of over 40%, it can be stamped into ultra-thin foils down to 0.03mm for flexible circuit board substrates.

Q:How does OFC/OFHC support signal and magnetic applications?

OFC coaxial cables reduce high-frequency signal attenuation for millimeter-wave radars, while OFHC coils near zero resistance to support superconducting magnets like MRI systems.
