MITSUBISHI MATERIALSCopper & Copper Alloy Business



Leading the world with high-performance products and contributing to a sustainable society

Copper, which has excellent electrical and thermal conductivity, is indispensable in a wide range of fields such as automobiles, electronics, robots, and industrial equipment.

Our Copper & Copper Alloy Business uses copper cathode produced at our own smelter as a stable raw material to manufacture high-value-added copper & copper alloy products such as billets & cakes, wire rods, strips & sheets, and rods.

Aiming to be a global first supplier and the first choice of our customers, we focus on identifying customer needs and providing products and services that exceed their expectations.

Our core competence is the development and manufacturing technology of oxygen-free copper and copper alloys. By utilizing our expertise and experience accumulated through years of R&D and technological innovation, we have developed, manufactured, and sold high-quality & high-performance products.

In particular, in order to meet the increasing demand for copper, driven by growth in demand for automobiles and semiconductors, we are increasing overall production capacity by approximately 30% through investments at each site, with full-scale operations in 2026.

Furthermore, we will establish a global supply system through mutual cooperation with the Luvata Group, which operates in six countries around the world in the downstream field of copper processed products.

In recent years, as interest in global environmental issues has increased, our Copper & Copper Alloy Business is proactively introducing innovative technologies to reduce environmental impact and creating environmentally friendly products to contribute to the realization of a sustainable society.

We will continuously work together with our development, manufacturing, and sales departments to sincerely address customer needs, and provide high-quality & high-performance products, thereby growing together with our customers and achieving sustainable growth that contributes to the development of a sustainable society.
