C10100 Copper Coil is a high-purity oxygen-free electronic copper coil conforming to ASTM standards, with a minimum copper purity of 99.99% and extremely low oxygen content. It provides ultra-high electrical and thermal conductivity, excellent ductility, and superior formability for rolling, bending, and stamping. It resists hydrogen embrittlement and performs stably in high-temperature and vacuum environments. The coil features uniform thickness, smooth surface, and precise dimensional tolerance, making it an ideal material for high-end electronics, precision components, and applications requiring extreme purity and reliability.
