Frequently Asked Questions (FAQ)
What makes C10100 oxygen-free copper resistant to hydrogen brittleness?
C10100 oxygen-free copper contains no grain boundary oxide, which prevents reactions with hydrogen that typically form bubbles. This makes it highly stable and suitable for vacuum tubes and particle accelerators.
Can this material be used for ultra-thin electronics?
Yes. Due to its super ductility with an elongation rate of over 40%, it supports stamping into ultra-thin foils as thin as 0.03mm, making it ideal for flexible circuit board (FPC) substrates.
How does C10100 perform in high-temperature environments?
It offers excellent high temperature resistance with no risk of grain boundary oxidation below 400℃, making it suitable for semiconductor sputtering target high-temperature coatings.
Why is C10100 preferred in semiconductor chip manufacturing?
In chip manufacturing, C10100 oxygen-free copper targets deposit uniformly, which significantly improves the overall yield and reliability of the wafer metallization layer.
What is the advantage of using OFC/OFHC in cables and magnets?
OFC coaxial cables reduce signal attenuation for stable millimeter-wave radar data transmission, while OFHC coils feature resistance approaching zero, supporting the efficient operation of MRI magnets.
