Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its extensive applications, attributed to its versatility and cost-effectiveness compared to other high-performance ceramics. Alumina is distinguished by its excellent electrical insulation resistance, high-temperature endurance, robust hardness, wear resistance, and chemical stability. This makes it an excellent choice for applications that require resilience to high temperatures and corrosive environments.
Our factory specializes in alumina parts with purities spanning from 75% to an impressive 99.8%. Each ceramic component is meticulously crafted through processes like dry pressing, hot pressing, ceramic injection molding, and ISO pressing to ensure a dense body. To further enhance performance for unique applications such as fitting, friction reduction, and insulation, we offer secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We proudly manufacture an extensive range of alumina ceramic rings, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you require prototypes or high-volume production, you can rely on us to deliver a solution that meets your exact specifications.
