As an OFHC & OFE copper manufacturer, We can custom-made of grades C10100 & C10200 in a variety of shapes including bars, pipes, tubes, wires and sheets.
Oxygen-free copper is produced by the direct conversion of selected refined cathodes and castings under carefully controlled anaerobic conditions to prevent any contamination of pure, oxygen-free metal during processing. Characteristics of oxygen-free copper alloys are high electrical and thermal, high ductility, ease of welding, high impact strength, and low volatility under high vacuum.
C10100 Oxygen-Free Electronic Copper, also known as OFE, is a 99.99% pure copper with 0.0005% oxygen content. C101 achieves a minimum 101% IACS conductivity rating. This copper is finished to a final form in a carefully regulated, oxygen-free environment. C10100 OFE has High ductility, high electrical and thermal conductivity and low volatility under high vacuum.
High Conductivity (OFHC) Copper characteristics are high ductility, high electrical and thermal conductivity, high impact strength, good creep resistance, ease of welding, and low volatility under high vacuum.
