Silicon nitride (Si3N4) is a material with high fracture toughness and excellent thermal shock resistance, 

and in recent years it is also used as a substitute for molds. 

  • Thermal Shock Resistance 
  • High temperature strengthWear Resistance
  • Corrosion Resistance
  • Electrical Insulating properties
  • High Fracture Toughness

Main Applications:

  1. Molding mold parts (hot forging molds, various molds) 
  2. Casting parts (low pressure castings, various metal melting furnace equipments) 
  3. Die casting machine parts (plungers, sleeves, goosenecks) 
  4. Welding machine parts (guide pin for resistance welding, guide roll for steel pipe weldings) 
  5. Crusher parts (classifiers, airflow type crushers, beads mills) 
  6. Wear resistant parts (wire drawing machine guide rollers, motor shafts, bearings, fishing line yarn paths, wire drawing capstans) 
  7. Semiconductor manufacturing equipment parts (stage parts, linear motors parts)


Silicon nitride (Si3N4) is a gray ceramics, it has excellent resistance to thermal shock resistance,

and it has a property that it is comparatively hard to get wettability with molten metal.By utilizing these characteristics, 

it is used for components used in harsh environments such as internal combustion engine parts of automobiles and torch nozzles of welding machines, especially in harsh environments.
