Oxygen Free Copper Tube-C10200- 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 are high electrical and thermal, high ductility, ease of welding, high impact strength, and low volatility under high vacuum.
