Carbon materials · Japan and worldwide
Graphite, carbon brushes and composites for your application
For semiconductor, industrial machinery and aerospace applications worldwide. In 1974, we became the first company worldwide to mass-produce isotropic graphite.
Materials and support for your application
Isotropic graphite
Graphite products for semiconductor manufacturing, industrial furnaces, continuous casting and electric discharge machining.
Carbon brushes
Carbon brushes supply electricity through sliding contact in motors used in vacuum cleaners, washing machines and power tools.
C/C composites
C/C composites are used in the ion-engine grids of the asteroid probes Hayabusa and Hayabusa 2.
Coated graphite
TaC (tantalum carbide) and SiC (silicon carbide) coatings add properties to graphite and expand its applications.
