Aluminum Titanate Ceramic Riser Tube Overview

Aluminum titanate ceramic riser tubes are essential components used in low-pressure casting machines. Thanks to their low thermal expansion coefficient, excellent thermal shock resistance, and non-wettability to molten aluminum, these tubes effectively overcome the limitations of traditional steel riser tubes, such as poor thermal shock resistance, low corrosion resistance, short service life, and frequent replacements. These advantages make aluminum titanate ideal for manufacturing riser tubes used in continuous, high-quality casting processes.
