C102 is a high-purity oxygen-free copper (≥ 99.95% Cu), with a purity slightly lower than C101. It also offers excellent electrical conductivity, thermal conductivity, and ductility. Its low oxygen content makes it resistant to hydrogen embrittlement, suitable for special operating conditions such as vacuum environments, heating applications, and reducing gases.
