7. Business Fields A wide variety of business fields supporting everything from domestic life to industry Toyo Tanso carbon products are hard at work in a range of fields from semiconductors, automobiles, and industrial machinery to home electronics, medical equipment, and aerospace. The range of arenas in which our carbon products are active has expanded steadily since our inception. To realize the various needs of a wide array of industries, we have engaged in round after round of trial and error. This hard work has borne fruit and we currently cover a wide range of fields extending from products and services for day-to-day life to those for industrial applications.

Semiconductors: Carbon products are valued for their heat resistance, chemical resistance, and high purity. They perform reliably in harsh environments where gases and chemicals are used at high temperatures. Applications include manufacturing processes for monocrystalline silicon, compound semiconductors, next-generation semiconductors, and photovoltaic cells.

Home Electronics: Carbon has a range of desirable characteristics including excellent thermal and electrical conductivity and self-lubricating properties. It is being used as an important component that enables many functions in home electronics products, supporting domestic life.

Industrial Machinery: Carbon serves as a vital material in die manufacturing, industrial machine parts, metal casting, furnaces, hot presses, and bearings.

Nuclear Power: Our products are now applied in nuclear power, including high‑temperature gas reactors and nuclear fusion reactors.

Aerospace: Carbon products are gaining recognition in cutting‑edge aerospace applications, such as rocket components.

Medical Care: Carbon applications are expanding in medicine, including X‑ray target materials for CT scanners.

Automobiles: Significant quantities of carbon are used in parts and manufacturing components for transportation equipment, where consistent quality and reliability are critical.

Rail and Shipping: Our proprietary carbon strips for pantograph contacts are deployed in the field, markedly reducing contact‑wire wear. Toyo Tanso will continue to explore new opportunities, drawing on the knowledge and technical expertise we have built over the years.
