What Is an Aluminum Titanate Sprue Bushing?
An aluminum titanate sprue bushing is a ceramic component used in selected low-pressure aluminum casting systems.
The sprue bushing forms part of the molten metal passage and connects the furnace-side molten aluminum transfer path with the casting system. Because it operates in a high-temperature environment and may experience repeated heating and cooling, the material and dimensions need to be matched to the actual casting equipment.
Aluminum titanate is used for selected aluminum casting applications where its thermal properties and interaction with molten aluminum are suitable for the operating conditions.
Applications
Aluminum titanate sprue bushings can be used in selected applications including:
- Low-pressure aluminum casting
- Aluminum alloy wheel casting
- Aluminum automotive component casting
- Molten aluminum transfer systems
- Low-pressure casting equipment
- Customized aluminum casting equipment
The actual suitability of the product should be evaluated according to the equipment design, aluminum alloy, working temperature, thermal cycling, and other operating conditions.
Why Use Aluminum Titanate for a Sprue Bushing?
Aluminum titanate is used in selected high-temperature ceramic applications because of its combination of thermal properties.
Depending on the specific product formulation and application, relevant considerations may include:
- Low thermal expansion
- Thermal shock resistance
- High-temperature stability
- Suitability for molten aluminum applications
- Resistance to repeated thermal cycling
Material selection should be based on the actual operating conditions rather than material name alone.
Customized Sprue Bushing Dimensions
Sprue bushings used in low-pressure casting equipment may have different dimensions and connection configurations.
SF-Foundry can evaluate customized requirements according to customer drawings, dimensions, or existing components.
Depending on the equipment design, customization may include:
- Outside diameter
- Inside diameter
- Overall length
- Wall thickness
- Connection dimensions
- Installation dimensions
- Special end configurations
If you are replacing an existing sprue bushing, providing the original drawing or detailed measurements can help us identify the required configuration.
