What Is Aluminum Titanate Ceramic?
Aluminum titanate ceramic (Al₂TiO₅) is a specialized oxide ceramic known for its very low thermal expansion, strong thermal shock resistance, and non-wetting behavior to molten aluminum. It is produced by reacting alumina and titania at high temperatures to form a stable micro-porous structure that remains dimensionally consistent under rapid heating and cooling.
Aluminum Titanate Ceramic (Al₂TiO₅) Advantages
The durable microstructure of Al₂TiO₅ allows components such as riser tubes, stalk tubes and sprue bushes to remain operational for longer intervals. This reduces replacement frequency, lowers total consumable cost and helps maintain stable casting performance across extended production cycles.
Aluminum titanate ceramic supports smoother aluminum transfer in LPDC and gravity casting systems, helping minimize turbulence, oxide entrapment and filling inconsistencies. The result is fewer defects, more stable melt flow behavior and improved casting consistency across repeated cycles.
Its predictable dimensional behavior and compatibility with molten-aluminum hardware lessen mechanical load on mounting interfaces, seals and refractory transitions. This helps prevent premature wear on surrounding equipment, contributing to lower maintenance requirements and better long-term system reliability.
The lightweight structure and consistent geometry of Al₂TiO₅ parts make them easier to handle, align and install. This shortens changeover time during scheduled maintenance and accelerates production restarts, supporting higher overall equipment efficiency.
Aluminum Titanate Ceramic Properties
Aluminum titanate ceramic (Al₂TiO₅) provides exceptionally low thermal expansion, strong thermal shock resistance and non-wetting behavior to molten aluminum, delivering stable performance and dimensional reliability in casting environments.

Key Features of Aluminum Titanate Ceramic
The Al₂TiO₅ microstructure tolerates rapid temperature swings between ambient and molten aluminum without cracking. This makes the material suitable for frequent start–stop cycles in low pressure die casting, dosing furnaces and launder systems.
Molten aluminum does not readily wet aluminum titanate surfaces, which reduces metal build-up, oxide adhesion and contamination in the flow path. Cleaner internal surfaces support smoother metal transfer and more stable filling behavior.
Under continuous molten-aluminum exposure, aluminum titanate maintains its geometry and structural integrity over long service periods. Stable dimensions reduce the risk of leakage, misalignment and premature failure at critical interfaces.
Compared with many dense refractories, aluminum titanate ceramic has relatively low thermal conductivity. This helps limit heat loss along riser tubes, spouts and other transfer components, improving thermal efficiency and temperature control in casting operations.
Aluminum titanate ceramic exhibits a very low coefficient of thermal expansion, so dimensional change under operating temperatures is minimal. This helps riser tubes, stalk tubes and sprue bushes stay aligned with dies, seals and furnace nozzles during repeated heating and cooling.
Aluminum titanate ceramic can be engineered into riser tubes, stalk tubes, sprue bushes, pouring cups, spouts, rings and other custom shapes. This flexibility allows foundry and LPDC engineers to match component design precisely to furnace layouts and casting equipment.

Aluminum titanate ceramic combines low thermal expansion, excellent thermal-shock resistance, and strong non-wetting performance, making it an ideal and cost-efficient choice for LPDC and molten-aluminum casting.
Silicon nitride provides higher mechanical strength but at a much higher cost, while fused silica is economical but lacks dimensional stability and durability under thermal cycling.
| Performance Factor | Aluminum Titanate Ceramic (Al₂TiO₅) | Silicon Nitride (Si₃N₄) | Fused Silica |
|---|---|---|---|

Yes. Aluminum titanate (Al₂TiO₅) is specifically valued for its exceptional thermal-shock resistance. Its unique crystal structure and extremely low thermal expansion allow it to tolerate sudden heating and cooling without cracking. This makes it well-suited for:
intermittent casting cycles
start-stop LPDC/HPDC operations
repeated immersion and withdrawal from molten aluminum
In demanding casting environments where temperature swings are unavoidable, aluminum titanate maintains structural stability far better than fused silica or standard refractories.
Aluminum titanate ceramics can tolerate moderate mechanical vibration during normal casting operation because of their low elastic modulus and inherent thermal-stress damping behavior. However, they are not designed for high-impact loads, strong mechanical shocks or continuous side loading.
To maximize service life of riser tubes, sprue bushings and pouring components:
ensure proper axial alignment and avoid lateral forces
use support fixtures or seals that prevent rigid clamping
minimize impact during installation and removal
With correct mounting and controlled loading conditions, aluminum titanate components deliver stable performance and long service life in LPDC and molten-aluminum handling systems.
Common factors include thermal shock beyond design limits, incorrect mounting, mechanical overload, metal infiltration from improper alloy cleanliness or temperature spikes.
No. Once cracked, aluminum titanate parts cannot be structurally repaired. Replacement ensures process stability and casting quality.
High-quality producers control density, porosity, phase composition and shrinkage rate, ensuring predictable expansion behavior, improved lifetime and minimal dimensional variation between batches.
Provide drawings, key dimensions, tolerances, thermal conditions, alloy temperature and expected cycle load. This allows accurate pricing and selection of the proper aluminum titanate ceramic grade.
