Application
π Foundry & Metallurgy ο½ Molten Metal Handling Applications
In molten metal handling applications, Aluminium Titanate ceramics are widely used for riser tubes, nozzles, pouring cups, launders, and thermocouple protection sheaths. These components maintain structural integrity when repeatedly exposed to high-temperature molten metals, while also preventing contamination of the melt. Their ability to provide accurate and stable temperature measurement in molten aluminum, copper, and related alloys further enhances process control in foundry and metallurgical operations.
π Automotive Industry ο½ High-Temperature Welding and Engine Components
Within the automotive industry, Aluminium Titanate ceramics play a critical role in resistance welding and high-temperature assembly processes. Components such as welding pinch rolls and pads are essential for body-in-white assembly lines, where they must withstand intense localized heat and avoid reacting with zinc coatings on galvanized steel. In addition, Aluminium Titanate shows strong potential for use in selected engine components, including exhaust port liners and other parts requiring thermal insulation and high shock resistance.
π¬ Industrial & Chemical Processing ο½ High-Temperature Structural Components
Beyond metallurgical and automotive applications, Aluminium Titanate ceramics are also utilized in industrial and chemical processing environments. Typical uses include heat exchanger components exposed to rapid temperature changes, wear-resistant liners for high-temperature abrasive processes, and laboratory or instrumentation applications such as kiln furniture, setters, and trays. In all these applications, Aluminium Titanate ceramics provide reliable performance where minimal thermal expansion, chemical stability, and long service life are critical.

Frequently Asked Questions
Q
What makes Aluminium Titanate ceramics resistant to molten metals?
Aluminium Titanate ceramics possess a unique microstructure that provides exceptional chemical inertness toward molten aluminum and copper. Their non-wetting surface characteristics prevent metal adhesion and erosion, while their ultra-low thermal expansion coefficient minimizes thermal stress during rapid temperature changes, ensuring structural integrity even under prolonged exposure.
Q
What is the difference between High-Purity Aluminium Titanate and Corundum Aluminium Titanate Composite?
High-Purity Aluminium Titanate (AlβOβ 56%, TiOβ 40%, Stabilizer 4%) offers ultra-low thermal expansion and excellent thermal shock resistance, making it ideal for applications with severe temperature cycling. The Corundum Aluminium Titanate Composite incorporates 30% Corundum, which raises the operating temperature ceiling and improves high-temperature mechanical strength for more demanding structural applications.
Q
In which foundry applications are Aluminium Titanate ceramics most commonly used?
In foundry and metallurgical operations, Aluminium Titanate ceramics are most commonly used for riser tubes, nozzles, pouring cups, launders, and thermocouple protection sheaths. These components benefit from the material's ability to withstand repeated thermal cycling and direct contact with molten aluminum, copper, and related alloys without degradation or melt contamination.
Q
How do Aluminium Titanate ceramics benefit automotive manufacturing processes?
In automotive manufacturing, Aluminium Titanate ceramics are used in resistance welding components such as pinch rolls and pads on body-in-white assembly lines. They withstand intense localized heat and do not react with zinc coatings on galvanized steel, preventing contamination and extending component service life. They also show potential for exhaust port liners and other engine parts requiring thermal insulation and high shock resistance.
Q
Can Aluminium Titanate ceramics be used in chemical processing and laboratory environments?
Yes. Aluminium Titanate ceramics are well-suited for industrial and chemical processing environments. They are used in heat exchanger components subject to rapid temperature fluctuations, wear-resistant liners in high-temperature abrasive processes, and laboratory applications including kiln furniture, setters, and trays β wherever chemical stability, minimal thermal expansion, and long service life are essential.
Q
How do Aluminium Titanate ceramics help reduce operational downtime and maintenance costs?
Due to their superior thermal shock resistance, chemical stability, and resistance to molten metal erosion, Aluminium Titanate ceramic components experience significantly less wear and degradation compared to conventional refractory materials. This translates to longer service intervals, fewer component replacements, and reduced unplanned downtime β ultimately improving process efficiency and lowering total cost of ownership for foundry, automotive, and industrial operations.
