Since its inception in July 1947, Toyo Tanso has consistently devoted itself to the development, manufacturing, and sales of high-performance carbon products that use coke as the base material. For example, in 1974, the company successfully mass-produced large-size isotropic graphite ahead of domestic and overseas rivals. Its products offer excellent conductivity (thermal/electrical) and durability (thermal/chemical), and are also lightweight and easy to machine.
