Aluminum titanate ceramic structural components are high-performance parts made from aluminum titanate (Al₂TiO₅), a material recognized for its low thermal expansion, excellent thermal shock resistance, and superior resistance to corrosion by molten metals. These components are widely used in non-ferrous metal casting and high-temperature industrial processes where stability, durability, and resistance to thermal stress are essential. Typical applications include riser tubes, pouring cups, spouts, and other structural parts in aluminum foundries and casting systems.
