High Purity 99.9% Enameled Pure Copper Wire

OCC silver is widely used in the production of high-end audio cables, where its superior conductivity and purity play a vital role in delivering unparalleled sound quality. The absence of grain boundaries in OCC silver ensures electrical signals pass through the cable with minimal resistance, resulting in clearer, more accurate audio output. In addition, OCC silver is used to manufacture high-performance connectors and interconnects, where it is highly valued for its superior conductivity and reliability.
