Our Aluminium Titanate ceramics are expertly formulated to operate in harsh working conditions involving severe thermal cycling and exposure to corrosive molten metals. They demonstrate outstanding resistance to molten aluminum and copper, preventing wetting, erosion, and chemical degradation. As a result, components manufactured from Aluminium Titanate deliver superior durability, reduced maintenance requirements, and extended service life, helping customers minimize downtime and improve overall process efficiency.
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.
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.
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.

Aluminium Titanate ceramics possess an inherently low surface energy and non-wetting behavior toward molten aluminum and copper. Their chemical inertness prevents reactions with the melt, while their microstructure provides resistance to erosion and corrosion, ensuring long-term integrity in direct contact with molten metals.
High-purity Aluminium Titanate ceramics can typically withstand continuous operating temperatures up to approximately 1350°C. Corundum Aluminium Titanate composite materials are formulated for even higher operating temperatures and improved high-temperature mechanical strength, making them suitable for more demanding thermal environments.
Aluminium Titanate has one of the lowest coefficients of thermal expansion among advanced ceramics, which greatly reduces thermal stress during rapid heating or cooling cycles. This ultra-low expansion characteristic gives it exceptional thermal shock resistance, allowing components to survive repeated temperature fluctuations without cracking or spalling.
Aluminium Titanate ceramics are well-suited for resistance welding components such as pinch rolls and pads used in body-in-white assembly lines. They resist the intense localized heat generated during welding and do not react with zinc coatings on galvanized steel. They are also considered for exhaust port liners and other engine parts that require thermal insulation and resistance to mechanical shock.
High-Purity Aluminium Titanate (Al₂O₃ 56%, TiO₂ 40%, Stabilizer 4%) is optimized for ultra-low thermal expansion and excellent thermal shock resistance. The Corundum Aluminium Titanate Composite incorporates approximately 30% corundum, which increases the material's operating temperature ceiling and enhances high-temperature mechanical strength, making it suitable for applications that demand both thermal stability and structural performance at elevated temperatures.
Yes. Aluminium Titanate ceramics are chemically stable and resistant to many corrosive environments, making them suitable for use in chemical processing equipment such as heat exchanger components, wear-resistant liners, and kiln furniture. In laboratory settings, they are used as setters and trays where dimensional stability, low reactivity, and resistance to repeated thermal cycling are essential.
