Oxygen Free Conductivity Copper Rod

Oxygen Free High Conductivity Copper (OFHC) is produced by the direct conversion of refined high quality Copper Cathode.LME Grade A (purity 99.95%),by melting & casting under strictly controlled conditions under vacuum or CO gas oxidization in or to prevent air exposure during processing.

Oxygen Free High Conductivity (OFHC) insures extra high grade or copper wire with oxygen content less than 10 ppm. OFHC has a higher electrical & thermal conductivity, higher recrystallization temperature and workability than normal copper.

The application of OFHC is widely spread over electrical & electronic equipments which is requires a high efficiency, accurate and durable material. Chandra Proteco Ltd. Has been manufacturing OFHC by UP-CAST process and supplying high quality copper for ultra high voltage transformer winding coils according to the Customera s requirement.
