Occ (the continuous molding of ohno) is the name given to the casting process developed to help eliminate grain boundaries in copper or silver with a unique patented process. The occ casting method uses specialized heated molds in order to draw a single crystal up to 125 meters in length. With just a single crystal at very long lengths, there is an unhindered free path for the best possible signal transfer. Along with this unique superior long crystal structure, occ provides copper and silver with the least possible oxides and other impurities. In contrast to occ, there are other lower grade coppers such as ofc, etp with a multitude of grain boundaries and other impurities.
