China Supplier Infrared Transmission - Single Crystal Silicon Ingot – WMC

Copper is reddish purple color metal material with characteristic of malleable and ductile, excellent conductor of heat, robust construction and less oxidation. High Purity or Ultra High Purity Copper 99.999%, 99.9999% purity 5N 6N by vacuum smelting and zone-refining is uniform equiaxed grain, consistant microstructure, corrosion resistance, low softening temperature and good surface performance. With very unique properties different from ordinary copper inogt, It is used to prepare high purity copper targets for functional coating of components,  for high purity copper tubes, microelectronics, TFT-LCD, integrated circuits, to make high purity copper rod by vacuum continuous casting, to prepare bonding wires for electronic packaging and high quality audio cable, etc. High Purity Copper 5N 6N can also be directly used as additive element in the development of super alloy and new alloy in aviation and aerospace and atomic industry, as well as the analysis of standard samples and high purity copper foil preparation by standard machining process is for shielding material of atomic reactor.

Generally, High Purity Copper is primarily used in the manufacturing of electronic semiconductor devices and elements, large scale electron tubes in telecommunication industry, special alloy materials, sputtering targets, rectifying elements, biologic medicine, in coating process, and calibration specimens in metal analysis field and electronic chemical industry. High Purity Copper at Western Minmetals (SC) Corporation with 99.999%, 99.9999% 5N 6N purity can be delivered in form of  bar, ingot, plate and nugget or as customized specification.
