Application Areas
Aluminum titanate riser tubes are used in a variety of aluminum casting production processes. They are suitable for complex thin-walled castings, large-size castings, high-precision alloy aluminum castings, large aluminum castings, and automated batch casting production with high temperature, high purity, and high surface quality requirements. They ensure stable aluminum liquid flow and transportation under high pressure and high cycle conditions, and reduce the risk of riser tube cracking.
Such as high-precision castings such as automobile wheels, engine cylinders, and aerospace structural parts.
Product Advantages
Super strong thermal shock resistance, extremely low thermal expansion coefficient, adapt to frequent temperature rise and fall during casting, and reduce the risk of thermal stress cracking.
Resistant to aluminum liquid erosion, excellent corrosion resistance to aluminum and aluminum alloy melts, almost no adhesion, avoid residual metal slag or impurities on the tube wall, reduce pollution, and improve casting quality.
Aluminum titanate has strong high-temperature stability, the highest working temperature is 1500°C, long-term durability, and can operate stably in an aluminum liquid environment of 800~1200°C for a long time, ensuring stable aluminum liquid delivery pressure and improving casting consistency.


Why choose SF-Foundry Riser Tubes?
♦ Longer service life – Compared with silicon carbide riser tubes, the service life is increased by more than 10% under the same working conditions, reducing the frequency of replacement.
