Aluminum titanate ceramic pouring ladles are high-performance refractory tools designed for handling and transferring molten aluminum and other non-ferrous metals. Made from aluminum titanate (Al₂TiO₅), these ladles offer excellent thermal shock resistance, low thermal conductivity, and strong resistance to wetting by molten metals. They are ideal for foundries and metal casting processes where precise pouring and minimal contamination are critical. Their durability and ability to maintain structural integrity at high temperatures make them reliable for melting and pouring operations in various metallurgical applications.
