Copper and Copper Alloy Business

In the copper processing sector, we produce wrought copper products such as terminal connector materials for automobiles, electrical wires and copper tubes. We also apply our advanced technological capabilities to produce oxygen-free copper, oxygen-free copper alloys and other special copper alloys, which we supply globally.
In the precious metals department, we offer an accumlation plan called "My Gold Partner" for gold, silver and platinum, providing an alternative for private investors' asset building.

To become the world's most profitable company in the copper processing sector, we are expanding sales in emerging markets of MNEX, a new copper alloy. By also setting up a slitter business and sales facilities in emerging markets, we are cultivating the market for our unique alloys.

Our Metals Business got its start in 1873, when Mitsubishi founder Yataro Iwasaki acquired and began operations at the Yoshioka Mine in Okayama Prefecture. In 1887, we also acquired a mine in Osarizawa. Full-fledged smelting and refining operations commenced in 1896, when we acquired the Ikuno and Sado mines and a refinery in Osaka from the Japanese government.
