Aluminum Titanate

Aluminum Titanate(N-420) is composed of Al₂O₃ and  TiO₂.(Al₂TiO₅) This material had great non-wettability for molten metal. Widely used as a crucible for molten Aluminum.


  • Excellent high thermal resistance, High refractoriness (1500°)
  • Strongest resistance for rapid thermal.
  • Extremely low thermal expansion(0.7×10‐6/℃)
  • Excellent no-wettability for molten metal.
  • Machinable ceramics, possible to take a machining process on sintered ceramic body.


  • N-420 Aluminum Titanate material is the strongest ceramic for rapid thermal because it has a high refractoriness and a low coefficient of thermal expansion.
  • N-420 Aluminum Titante is applicable material as a burner tip,  a nozzle, and a crucible.
