Providing Stable Supply of Metal Materials and Recycling of Metal Resources as Our Mission

The roots of our Metals Business trace back to 1873 when the Company acquired the Yoshioka Mine. Metal materials such as copper are essential in many industries. We have supported the development of Japanese industry and society across centuries by providing metal materials. Our supply destinations have now expanded globally.
Furthermore, we have developed a recycling system for recovering metal resources such as gold, silver, tin, lead and bismuth not only from the so-called urban mine of printed circuit board waste and other scrap materials (E-scrap), but also by efficiently disassembling discarded products such as home appliances and automobiles and incorporating them in smelting and other processes.

Supporting the Industrial Infrastructure and Affluent Life with Our Exclusive Technologies

We process copper that we smelt into products of various shapes, such as terminal materials for automobiles, copper tubes for air conditioners, and semiconductor lead frames.
We will continue to contribute to the development of industrial and social infrastructure around the world by developing and supplying new products with high quality and performance based on our proprietary technologies.

Delivering Outstanding Development Skills and the On-Site Capabilities to Win out in the Business world
