Aluminum Titanate Ceramic Insulating Ring Overview

Aluminum titanate ceramic insulating rings are precision-engineered components made from aluminum titanate (Al₂TiO₅), designed for high-temperature applications involving molten non-ferrous metals. These insulating rings provide excellent thermal shock resistance, very low thermal conductivity, and strong resistance to wetting by molten aluminum. They help prevent metal adhesion and thermal fatigue, making them ideal for aluminum casting systems where thermal insulation, component protection, and reliable operation in harsh industrial environments are required.
