Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) presents a wide array of applications, celebrated for its adaptability and cost-efficiency compared to alternative advanced ceramics. Known for high electrical insulation resistance, superb temperature tolerance, impressive hardness, robust wear and chemical resistance, it is perfect for withstanding elevated temperatures and chemical exposure.
Our facility is adept at producing alumina parts with purities ranging from 75% to an impressive 99.8%. We ensure dense ceramic bodies using methods like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications involving fitting, friction reduction, and enhanced insulation, we offer post-sintering secondary processes such as CNC machining, polishing, glazing, and metalizing.
We specialize in a vast range of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Whether you require a prototype or large-scale production, we're committed to delivering tailored solutions that meet your exact requirements.
