Description of Alumina Ceramic Parts
Unlock the power of Aluminum oxide (Alumina), celebrated for its vast applications and cost-effective nature compared to other advanced ceramics. Alumina is renowned for its exceptional electrical insulation resistance, robust high-temperature resistance, remarkable hardness, outstanding wear resistance, and superior chemical stability, making it the prime material for high-temperature and chemically corrosive environments.
Our factory specializes in producing alumina parts with purities ranging from 75% to an impressive 99.8%. Each ceramic component is sculpted into a dense body through techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet unique application needs like fitting, friction reduction, and insulation enhancement, we offer post-sintering secondary processes, including state-of-the-art CNC machining, polishing, glazing, and metalizing.
We offer an extensive range of alumina ceramic components, from tubes, rings, and discs to rods, arms, and wire guides. Whether you require prototypes or are fulfilling high-volume demands, trust us to deliver tailored solutions that cater to your every requirement.
