The Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is extensively utilized due to its versatility and cost-effectiveness compared to other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, robust hardness, wear resistance, and excellent chemical stability, making it ideal for high-temperature and chemically corrosive environments.
Our factory offers a wide range of alumina purities from 75% to 99.8%. All ceramic parts feature a dense body achieved through dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet special application needs like fitting, friction reduction, and increased insulation, we offer secondary processes after sintering, including CNC machining, polishing, glazing, and metalizing.
We manufacture a diverse array of alumina ceramic rings, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you need prototyping or high-volume production, we are confident in providing the perfect solution for your requirements.
