Frequently Asked Questions
What is the purity of C10100 oxygen-free copper?
C10100, also known as Oxygen-Free Electronic (OFE) copper, has a purity of at least 99.99% with an oxygen content of less than 0.0005%.
Why is hydrogen brittleness resistance critical for vacuum equipment?
In vacuum environments, ordinary copper can react with hydrogen to form internal steam bubbles, leading to cracking. C10100 eliminates this risk due to its lack of grain boundary oxides.
Can C10100 be used for ultra-thin applications?
Yes, its superior ductility (elongation > 40%) allows it to be processed into ultra-thin foils as thin as 0.03mm, ideal for flexible printed circuits (FPC).
How does C10100 perform under high temperatures?
It maintains structural integrity and avoids grain boundary oxidation at temperatures below 400℃, making it suitable for semiconductor sputtering processes.
What are the benefits of using OFC in high-frequency cables?
OFC (Oxygen-Free Copper) significantly reduces signal attenuation and electrical noise, which is vital for high-speed data transmission like millimeter-wave radar.
Is C10100 suitable for cryogenic or superconducting applications?
Absolutely. Its high electrical and thermal conductivity at low temperatures makes it the preferred choice for superconducting magnets and MRI equipment.
