Chung Metal provides Copper C10300 Bars and Rods, an oxygen-free copper alloy designed for applications necessitating high purity and superior electrical performance. Featuring very low residual impurity and oxygen content, the alloy offers fine formability, high thermal stability, and consistent weldability. Produced under vacuum or controlled-atmosphere melting processes, our C10300 products provide consistency and performance in conductive applications that are critical.
C10300 contains ≥99.95% copper and ≤0.001% oxygen content. It has electrical conductivity of 101% IACS and good thermal conductivity. Its tensile strength is approximately 220–270 MPa, yield strength is approximately 70–90 MPa, and elongation is in the range 45–60%. It is ductile, weldable, and ensures good grain structure after annealing.
