An aluminum titanate riser tube is a ceramic component used in selected aluminum casting applications, particularly in systems where molten aluminum needs to be transferred through a ceramic tube under high-temperature operating conditions.
For casting equipment manufacturers and foundries, the material, dimensions, connection design, and operating conditions of the riser tube all need to be considered when selecting a suitable component.
This article explains what an aluminum titanate riser tube is, where it may be used, and what information you should provide when looking for a customized or replacement component.
What Is an Aluminum Titanate Riser Tube?
An aluminum titanate riser tube is a ceramic tube designed for use in selected molten aluminum handling and aluminum casting systems.
The tube provides a controlled passage for molten aluminum between different parts of the casting equipment. Its exact function and installation position depend on the equipment design and casting process.

Because the component is exposed to high temperatures and may experience repeated heating and cooling, ceramic material selection and dimensional accuracy are important considerations.
Aluminum titanate is one of the ceramic materials used for selected high-temperature aluminum casting applications.
Where Are Aluminum Titanate Riser Tubes Used?
Aluminum titanate riser tubes can be used in selected aluminum casting and molten metal handling systems.
Depending on the equipment design, applications may include:
- Low-pressure aluminum casting equipment
- Aluminum alloy casting systems
- Molten aluminum transfer systems
- Furnace-to-casting equipment connections
- Customized molten metal handling equipment
- Replacement ceramic tubes for existing casting equipment
The exact application should be confirmed according to the equipment structure and operating conditions.
A riser tube used in one casting system may have significantly different dimensions or connection requirements from a component used in another system.
Why Is Aluminum Titanate Used for Riser Tubes?
Aluminum titanate is used in selected high-temperature ceramic applications because of its thermal characteristics.
For aluminum casting applications, factors that may be considered when selecting an aluminum titanate ceramic component include:
- Thermal expansion
- Thermal shock resistance
- High-temperature stability
- Repeated heating and cooling
- Interaction with molten aluminum
- Component geometry and wall thickness
However, material selection should not be based on the ceramic material alone.
The actual suitability of a riser tube depends on the complete operating environment, including the casting equipment, aluminum alloy, temperature, molten metal flow, installation method, and thermal cycling conditions.

Why Are Riser Tube Dimensions Important?
A riser tube is not simply a standard ceramic tube.
Its dimensions need to match the equipment in which it is installed.
Important dimensions may include:
- Outside diameter
- Inside diameter
- Overall length
- Wall thickness
- Connection dimensions
- Installation position
- End configuration
For some applications, even a small dimensional difference can affect installation or compatibility with the existing equipment.
This is why customized manufacturing may be required when replacing an existing riser tube.
Custom Aluminum Titanate Riser Tubes
Casting equipment does not always use a standard-size riser tube.
If you need a customized aluminum titanate riser tube, a technical drawing is the most useful starting point.
If a drawing is not available, you can also provide:
- Photos of the existing component
- Outside and inside dimensions
- Overall length
- Wall thickness
- Equipment information
- Application information
- Previous supplier specifications
- Required quantity
This information allows the supplier to better understand the component before confirming a quotation.
When Should You Consider a Replacement Riser Tube?
A replacement may be required when the existing ceramic component:
- Has reached the end of its expected service period
- Has visible damage or cracks
- No longer fits the equipment correctly
- Has undergone dimensional changes
- Is no longer available from the original supplier
- Needs to be replaced with a customized component
Before ordering a replacement, it is important to confirm the original component dimensions and actual operating conditions.
Simply ordering a tube with the same outside diameter may not be sufficient if the internal diameter, length, connection, or installation configuration is different.
