6N super high purity electrolytic copper refers to copper with its chemical purity reaching 99.999% (5N) and the gas elements like C, N, O, H and S meeting the requirements of semiconductor, based on analysis of at least 40 impurity elements. Currently GRIKIN Advanced Material Co., Ltd. has finished constructing national largest industrialized production line of 6N super high purity copper capable of producing 100 ton/year, becoming the only enterprise realizing stable industrialized batch production of 6N super high purity copper. Its products first applied in the production of domestic high performance sputtering target material and evaporation material, breaking foreign monopoly of super high purity raw material used in the electronic information industry.
