About JX金属
JX金属株式会社 (JX Advanced Metals Corporation) is a globally active non-ferrous metals company headquartered in Tokyo that emerged from the Hitachi mine. The company produces and sells high-technology materials based on copper and rare metals: sputtering targets for thin-film applications, rolled and electrolytically produced copper foils, copper alloys (tungsten-copper, copper-nickel-zinc, phosphor bronze), tantalum and niobium materials, compound semiconductor substrates (InP, CdZnTe/CdTe), metal and ceramic powders as well as high-purity metals. In addition, there are resource extraction, copper and precious metal smelting, and metals and recycling business including the disposal of low-concentration PCB waste. Customer industries include semiconductors and sensors, printed circuit boards, displays, batteries, telecommunications, optics, connectors, magnetic materials, 3D printing and thermal management. In addition to its Japanese production sites in Ibaraki, Kanagawa and Oita, the company maintains offices in Santiago, Frankfurt am Main and Johannesburg.
