– Creamic MgO･Al2O3･SiO2 is formed by cordierite crystal 2MgO･2Al2O3･5SiO2. This material has two type, we called it N-23 and N-53.
-Especially, N-53 has more Nishimura’s originality. N-53 has a self-gazed wonderful appearance.
Feature
-High thermal shock resistance
-Low thermal expansion
Application
-Thermal resistance parts (Air heater, Heater parts）
-low thermal expansion required parts
