Ceramic dosing tube plays an important role in the factory to produce high-quality products and reduce production costs.
Aluminum Titanate Dosage Tube has outstanding properties that make it ideally suited for applications involving molten aluminum, including complete resistance to wetting by aluminum alloys, total gas impermeability, and a very low thermal expansion coefficient. This material offers a longer service life and higher reliability when compared to cast iron, calcium silicate or fused silica components. All riser/stalk tubes are 100% leak-down tested, and parts are available with gasketing and ceramic foam filters to provide complete assemblies.
Aluminum Titanate Dosing Tube is a Material with Excellent Thermal Shock Resistance for low pressure die casting. 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 of Aluminum Titanate Dosage Tube is a result of the very low thermal expansion and a certain amount of porosity in the microstructure. The Aluminum Titanate Dosing Tube’s poor wettability with molten metal also makes it ideal for use in foundry technology and metallurgical melting.
Properties of Aluminum Titanate Dosing Tube
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 dosage tube 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.
