C10200 Oxygen-Free Copper

C10200, also known as Oxygen-Free Copper (OFC), is a high-purity copper grade with a minimum copper content of 99.95%. Unlike C10100 (Oxygen-Free Electronic Copper), C10200 has slightly higher oxygen content but still maintains excellent electrical conductivity, thermal conductivity, ductility, and corrosion resistance. It is widely used in electrical, industrial, and mechanical applications where high conductivity and workability are essential.

C10200 Copper Manufacturing & Heat Treatment Process

C10200 oxygen-free copper is commonly manufactured by casting, hot rolling, extrusion, and forging.

  • Forging temperature range: 760–870 °C
  • Annealing temperature range: 400–600 °C
  • Heat treatment: Usually supplied in annealed temper to maximize conductivity and formability
  • Workability: Excellent for cold forming, brazing, and soldering
  • Weldability: Good for gas shielded arc welding, limited suitability for resistance weldingAt Tiptop Forging, we specialize in producing C10200 forged bars, rings, and custom copper components, ensuring tight dimensional tolerances and reliable performance.
