Product Description

High purity copper cathode as adding elements can be directly applied in aviation, space atomic industrial super alloy, and the development of new alloy, as well as the analysis of the standard sample. It can also be through mechanical processing preparation into high purity copper foil shielding materials for atomic reactor. In addition, the high purity copper by vacuum melting become high purity copper ingot used in the preparation of high purity copper tube and microelectronics, TFT, LCD, IC and other components function coating with high purity copper target material .High purity copper or vacuum casting process can be made into high purity copper alignment pole, used for the preparation of electronic packaging with bonding line and high quality audio line.

Typical chemical analysis:

Metal Cu content in HPCu - 1 is not lower than *9.***9%;Li, Be, B, Na, Mg, AL, Si, P, S, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, zinc, Ge, As, Se, Zr, Nb, Mo, Ag, Cd, Sn, Sb, Te, Au, Hg, Pb, Bi, Th, U master impurity element content is not greater than the sum of 0.***1%;

HPCu - 2 metal Cu content in no less than *9.**9%;Li, Be, B, Na, Mg, AL, Si, P, S, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, zinc, Ge, As, Se, Zr, Nb, Mo, Ag, Cd, Sn, Sb, Te, Au, Hg, Pb, Bi, Th, U master impurity element content is not greater than the sum of 0.**1%.

· First, our workers cut, cleanout the *9.*5% pure copper material ,and then put them into the equipment  which can purify *9.****5% pure copper from *9.**5% pure copper material. In the purification process,our professional workers can control the electricity,the rate of circulation and temperature.And they also can put additive into the electrolyte.

· In short ,We mainly adopt electrolytic refining method which is used to obtain high purity copper.The pocess is highly purified of electrolyte with a higher purity of copper electrolysis again.

· Depending on the type of electrolyte, the system can be divided into three kinds. First, the copper sulfate solution;Second,copper nitrate solution;Third,copper sulfate solution and copper nitrate solution.
