TungstenMaterials Business Area

The Tungsten business of Mitsubishi Materials Corporation provides high-hardness and high-heat-resistance materials, mainly tungsten powder and carbide, and supports a wide range of industrial fields, including precision machining and wear-resistant applications. By leveraging its unique material development capabilities and quality control technologies, the business contributes to enhancing the performance of cutting tools and industrial machine components, supporting higher productivity and precision at production sites.
In addition, the business has built a global business foundation that covers everything from raw material procurement to product supply, contributing to the advancement of manufacturing by ensuring a stable supply of highly reliable materials.

The core strategy of the Tungsten business is to establish a resource-circulation model and enhance profitability in order to meet growing demand in the fields of next-generation batteries, defense, and electronic components. In order to reduce the risk of dependence on primary ore, which is highly unevenly distributed, the business aims to achieve a recycled raw material ratio of 100% at all production sites by the fiscal year ending March 2031, without reliance on specific regions. To this end, we are strengthening our global resource recycling network by increasing the amount of recycled material at H.C. Starck, our European base, establishing a new recycling site in the Americas, and utilizing our existing E‑Scrap collection routes. At the same time, by optimizing production systems to reduce fixed costs and expanding sales of high-value-added powder products, the business aims to ensure a stable supply and enhance profitability in the cemented carbide products and electronic materials fields.
