The History of JX USA

Building on the success of Seganoseki, Isohara Works was established in 1985. Located in Japan’s Ibaraki Perfecture, it was designed to serve the electronics material industry. The demand for the high purity metals used in the Semiconductor Industry was on the rise. To meet this growing demand, a manufacturing plant was opened in Chandler, AZ in 1991. It was designed to serve the Semiconductor industry in the U.S. and Europe. Today, JX Nippon Mining and Metals USA, Inc. is the industry leader in the production of Sputtering targets worldwide.
