Oxygen-Free Copper Rod

Oxygen-free copper rod for ultrafine wire drawing, made from ASTM B115 Grade 1 copper cathode.

  • Fine wire drawing with fewer breaks: no oxide particles.
  • Annealing in reducing atmospheres without embrittlement.
  • 101% IACS for high-efficiency conductors.

Alloy Alloying element What it adds Typical applications
CuAg0.10C10700 Silver 0.10% Higher softening temperature and creep resistance, with near-pure-copper conductivity. Windings, commutators, contact wire
CuSn0.30C14425 Tin 0.30% Higher strength and wear resistance, with good conductivity. Contact wire, high-strength conductors

CuAg0.10 and CuSn0.30 above are examples of the alloys we can produce. Alloying element content can be tailored to your requirements.
