C10200 Oxygen Free Copper (OFC) is a commercially pure copper grade with a minimum copper content of 99.95%, produced under oxygen-free conditions to achieve exceptionally low oxygen levels (typically below 0.001%). This eliminates the risk of hydrogen embrittlement and ensures outstanding electrical and thermal conductivity.
With an electrical conductivity of ≥101% IACS and thermal conductivity of approximately 391 W/(m·K), C10200 is the material of choice for applications demanding the highest purity, reliability, and performance in electrical, electronic, and industrial environments across South Africa and globally.
Key Advantage: C10200 OFC delivers superior conductivity, excellent weldability, and outstanding corrosion resistance — making it indispensable for South Africa's rapidly expanding power infrastructure, telecommunications, and renewable energy sectors.
Minimum 99.95% copper content with oxygen below 10 ppm for critical applications
Superior cold and hot workability for rods, bars, tubes, wires and sheets
