Keeping abreast of times, business markets demanded a finer grade carbon of more stable properties. Ahead of the rest of the industry, Toyo Tanso developed an "isotropic graphite" which is pressed by Cold Isostatic Press, having superfine isotropic microstructure. We have established world level technology that enables this isotropic graphite to fully exhibit its superior properties in the fields of nuclear power which requires high reliability, electrical discharge processing where accuracy is everything, and semiconductors which supports today's hi-tech wave.

Application

　
Toyo Tanso's special graphite products are highly regarded for their excellent performance and reliability and are used across a wide range of fields that are essential in our everyday lives.
In the environmental and energy industry, our products are used for solar cell manufacturing, atomic power and aerospace applications.
In the electronics industry, we provide materials for various manufacturing process such as polycrystalline silicon and single crystal silicon, white LEDs, and high-frequency device.
Basic applications of our products include industrial furnaces, continuous casting dies such as those for copper alloys, optical fibers, and EDM electrodes for mold manufacture.
