It is high-purity copper at the world’s highest level of 6N (purity approximately 99.9999%).
We have started the import and sale of high-purity copper at the world’s highest level of 6N (purity approximately 99.9999%). The manufacturer is CHANGZHOU XINGLONG HI-NEW METAL PRODUCTS CO., LTD, located in Changzhou, China, which has established a production system for 6N (purity approximately 99.9999%) high-purity copper with an annual output of 120 tons, making it the first Chinese manufacturer to do so. Generally, the purity of electrical copper supplied for electric wires and drawn copper products is 4N (99.99%). "High-purity copper" refers to copper that has significantly increased in purity through re-refining, and it is used in wiring materials for semiconductor devices, ultra-high-end audio equipment, biological medicine, sputtering target materials, damascene anodes, bonding wires, and more. Particularly in recent times, the miniaturization of semiconductors has rapidly advanced, and the demand for high performance in devices has become increasingly stringent, leading to a growing need for high-quality high-purity copper with fewer impurities and smaller variations in the amounts of each impurity.
