    Single Crystal Copper Wire (OCC)

    Single crystal copper wires (OCC) are conductors that have a purity level exceeding 99.9999%. Their high purity enhances electrical conductivity and reduces resistance, which makes them suitable for applications requiring reliable and efficient signal transmission. With a minimum diameter of 0.01mm, OCC wires are ideal for high-performance audio signal transmission, where precision and clarity are important. Their properties make them a preferred choice for industries focused on delivering optimal audio and electronic performance.

    Typical Applications
    • Internal wiring for electronic devices like smartphones and computers, including data signal cables for hard drives.
    • Critical components in integrated circuit packaging, supporting full copper lead frames and replacing traditional bonding wires.
    • High-performance audio signal transmission in sound systems, ensuring precision and clarity.
    • Communication cables designed to maintain stable and reliable signal transmission.

    Features
    • The resistance of single crystal copper is 8% to 13% lower than that of standard copper, providing higher conductivity. This makes it ideal for manufacturing high-fidelity audio and video signal cables, high-frequency digital signal transmission lines, and ultra-fine wires (0.01mm) used in the microelectronics industry.
    • Single crystal copper offers greater resistance to fatigue damage caused by repeated use or stress. This durability ensures a longer lifespan compared to polycrystalline copper.
