overcoat & topcoat
Overcoat/Topcoat Copper Conductors
Sark Wire manufactures overcoat (topcoat) copper conductors designed for applications requiring superior solderability, enhanced corrosion resistance, and reliable long-term performance.
Our overcoat conductors are produced using a specialized process in which individual strands are first tin-plated, then a continuous second tin layer is applied over the entire stranded conductor. This dual-layer process provides improved surface protection and consistent performance in demanding environments.
We produce overcoat copper conductors in a wide range of sizes, from fine gauges up to AWG 14, supporting both standard and custom requirements
