Aluminium Titanate Ceramics Plate Description
Aluminium Titanate Ceramic Plates are flat, high-performance ceramic components made from aluminium titanate (Al₂TiO₅), specifically designed for use in high-temperature environments involving molten non-ferrous metals. These plates are valued for their exceptional thermal shock resistance, low thermal expansion, and non-wettability with molten aluminium, which prevents metal adhesion and extends service life. Aluminium titanate plates are commonly utilised in casting systems, insulation barriers, and support structures, offering remarkable dimensional stability and durability under challenging thermal cycling conditions.
Applications of Aluminium Titanate Ceramic Plates
-Thermal insulation in casting systems:
Used as heat-resistant barriers or linings in facilities exposed to molten aluminium and high temperatures.
-Support plates in foundries:
Provide structural support for moulds, crucibles, or other ceramic components during the casting process.
-Base plates in low-pressure die casting (LPDC):
Serve as mounting or sealing plates in LPDC machines for stable and heat-resistant operation.
-Flow control assemblies:
Integrated into systems like sliders and nozzles to control and guide molten metal.
-Protective linings:
Act as wear-resistant, non-reactive surfaces in gutter systems and dosing chambers.
-Facilities for processing molten metal:
Utilised in facilities requiring high thermal resistance and non-wettability with aluminium, thereby contributing to prolonging the service life of the entire system.
