Purity level exceeding 99.9999%

Copper Conductor

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.
