  • product details
  • Aluminum Titanate Stoppers is a Material with Excellent Thermal Shock Resistance for flow control of molten masses. The special feature of aluminum titanate Al2TiO5 is its excellent thermal shock resistance. Components made of this material can withstand even the most abrupt temperature changes of several hundred degrees without damage, although they have low strength.

     

    The good thermal shock resistance is a result of the very low thermal expansion and a certain amount of porosity in the microstructure. The Aluminum Titanate Stoppers’s poor wettability with molten metal also makes it ideal for use in foundry technology and metallurgical melting.

     

    Properties of Aluminum Titanate Stoppers

    Excellent thermal shock resistance

    Max. Operating temperature: 900 °C

    Very low thermal expansion (<1x10-6K-1 between 20 and 600°C)

    High thermal insulation (1.5 W/mK)

    Low Young’s modulus (17 to 20 GPa)

    Good chemical resistance

    Poor wettability with molten metals

     

    Aluminium Titanate Al2TiO5 This material distinguishes itself by a unique combination of thermal and physical properties. High-purity aluminium oxide and titanium oxide are combined into a micro-porous material via a precision-controlled reaction sintering process. A structure characterized by a microfine system of fissures gives STA its unique performances characteristics. The extremely good thermal shock resistance is a result of the very low thermal expansion and a certain amount of porosity in the microstructure. This ceramic material’s poor wettability with molten metal also makes it ideal for use in foundry and metallurgical melting, especially in aluminium casting.

     

    Properties of Aluminum Titanate Stoppers

    Outstanding thermal shock resistance: temperature differences up to 900°C

    Anti-wetting properties

    Low thermal conductivity

    Very good chemical resistance / good corrosion resistance

    Low thermal expansion

     

    Products and Applications can find its applications in metallurgy in various forms:

    Riser Tubes for LPDC (low pressure die casting)

    Break rings for continuous casting of brass

    Nozzles / Bushes as casting mold inserts or mold joints

    Suction Tubes for vacural casting

    Dosage Tubes for dosing furnaces

    Sliding / Closing Plates, Stoppers, Spouts and Closing Systems for flow control of molten masses

    Plates, Saggers, Boats & Setters

    Ceramic Thermocouple Protection Tubes

    Vortex Finders, Thimbles & Dip Tubes

     

    STA also produces special components according to customer requirements made of Aluminium Titanate Ceramic: Spacers / Crucibles / Foundry Molds / Spouts / Rotors and Rotor Shafts / Protection Tubes / Special Components. We also provide OEM manufacturing for all customer all over the world.
