Main uses: 6N copper has some properties similar to gold, good conductivity, ductility, corrosion resistance and surface performance, and low softening temperature. As a new kind of material, high-purity copper is not only used in the preparation of high-purity analytical standard test materials, various connecting wires for electronic industry, bonding wires for electronic packaging, high-quality audio wires and integrated circuits, sputtering targets for liquid crystal display and ion coating, but also an indispensable and precious material in the atomic energy, rocket, missile, aviation, aerospace and metallurgical industries . As a new material, ultra pure copper has been paid more and more attention. In addition to the preparation of high-purity analytical standard test materials, various connecting wires for electronic industry, bonding wires for electronic packaging, high-quality audio wires and integrated circuits, sputtering targets and ion coating for liquid crystal display, high-quality audio circuits and other high-tech fields, high-purity copper is also used in atomic energy, rockets, missiles, aviation, space navigation and other fields Precious materials are indispensable in metallurgical industry. With the development of high and new technology and the need of strategic materials, high-purity metals have higher and higher requirements for purity. The preparation and application of high-purity and ultra-high-purity metals in modern materials science and engineering are new and growing fields.

High purity copper refers to metal copper with a purity of more than 4N. High purity copper has a very small grain boundary area, few lattice defects, some of its properties are similar to gold, with good conductivity, ductility, corrosion resistance and surface performance, while softening temperature is relatively low. High purity copper has high thermal conductivity and excellent processing performance at the base temperature. High purity copper is widely used in integrated circuit, electronic packaging, photovoltaic solar power technology and other fields. In recent years, with the development of high-tech industry, high-purity copper has been widely used. The preparation of high-purity copper is usually divided into two steps of purification and super purification. The preparation of high-purity copper generally takes crude copper as the raw material, and further removes the impurities to obtain 5n-7n high-purity copper. At present, the main methods of preparing high purity copper are area refining, anion exchange and electrolytic refining. The regional refining method is one of the main methods to prepare high-purity metals. At present, the regional refining methods of high-purity copper include floating regional refining method and desulfurization regional refining method
