Application
Foundry & Metallurgy｜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.
Automotive Industry｜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.
Industrial & Chemical Processing｜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
What makes Aluminium Titanate ceramics resistant to molten metals?
Aluminium Titanate ceramics possess an inherently low wettability with molten aluminum and copper, combined with strong chemical stability at elevated temperatures. This prevents erosion, wetting, and chemical degradation, making them ideal for direct contact with molten metal environments.
What are the typical applications of Aluminium Titanate ceramics in the foundry industry?
In foundry and metallurgical operations, Aluminium Titanate ceramics are commonly used as riser tubes, nozzles, pouring cups, launders, and thermocouple protection sheaths. These components ensure structural integrity and prevent melt contamination during repeated high-temperature exposure.
How does Aluminium Titanate perform in automotive manufacturing?
In the automotive industry, Aluminium Titanate ceramics are used in resistance welding components such as pinch rolls and pads, which must withstand intense localized heat without reacting with zinc coatings on galvanized steel. They are also suitable for exhaust port liners and other engine components requiring thermal insulation and shock resistance.
What is the difference between High-Purity Aluminium Titanate and Corundum Aluminium Titanate Composite?
High-Purity Aluminium Titanate (Al₂O₃ 56%, TiO₂ 40%, Stabilizer 4%) offers ultra-low thermal expansion and excellent thermal shock resistance, ideal for extreme cycling environments. The Corundum Aluminium Titanate Composite incorporates 30% Corundum to achieve a higher operating temperature ceiling and improved high-temperature mechanical strength.
Can Aluminium Titanate ceramics be used in chemical processing environments?
Yes. Aluminium Titanate ceramics are well-suited for industrial and chemical processing applications, including heat exchanger components, wear-resistant liners for abrasive high-temperature processes, and laboratory equipment such as kiln furniture, setters, and trays — wherever chemical stability and minimal thermal expansion are required.
How do Aluminium Titanate ceramics help reduce operational downtime?
Thanks to their superior thermal shock resistance, molten metal resistance, and extended service life, Aluminium Titanate ceramic components require less frequent replacement and maintenance. This directly reduces unplanned downtime, lowers maintenance costs, and improves overall process efficiency in demanding industrial operations.
