Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is highly versatile and cost-effective compared to other advanced ceramics. It offers high electrical insulation resistance, temperature resistance, strong hardness, wear resistance, and excellent chemical stability, making it ideal for high-temperature and corrosive environments.
Our factory produces alumina in varying purities from 75% to 99.8%. All ceramic parts have a dense body formed through dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For special applications requiring reduced friction, increased insulation, etc., we offer secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We manufacture a diverse array of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Whether for prototyping or high-volume production, we are confident in providing a solution tailored to your needs.
