OCC (Ohno Continuous Cast) is the name given to the casting process developed to help defeat annealing issues and virtually eliminate all grain boundaries in copper or silver with a unique patented process. The OCC casting method uses specialized heated moulds in order to draw a single crystal up to 125 meters in length. With only a single crystal in very long lengths, there is an unimpeded free path for the best possible signal transfer. Along with this superior single long crystal structure, OCC provides copper and silver with the least possible oxides and other impurities.
