N-600 low thermal expansion ceramics(Cordierite)

N-600 low thermal expansion ceramics have Zero thermal expansion near room temperature.

It has high strength and light weight compare to other low thermal expansion materials.

Nishimura can produce it into complex shape by green machining.

 

Features

  • Zero thermal expansion near room temperature(22-23℃)
  • Light weight and high strength
  • Because of its smooth surface, it can be mirror finished.
  • Zero water absorption
  • Low thermal conductivity

 

Applications

  • Semiconductor manufacturing device
  • Parts for inspection device
  • Standard gauge for proofreading)
  • Parts for machine used in high, or low temperature
