Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out with its extensive range of applications, owing to its remarkable versatility and cost-effectiveness compared to other advanced ceramics. Alumina is renowned for its superior electrical insulation, high-temperature resistance, robust hardness, wear resistance, and exceptional chemical stability, rendering it the ideal choice for demanding environments involving high temperatures and chemical exposure.
Our state-of-the-art production facility crafts alumina parts with purities spanning from 75% to an impressive 99.8%. Each ceramic component we offer boasts a dense structure achieved through advanced forming techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To further refine functionality for specialized applications such as fitting, friction reduction, and enhanced insulation, we provide sophisticated secondary processes post-sintering, including high-precision CNC machining, polishing, glazing, and metalizing.
We specialize in the manufacturing of an extensive range of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Catering to both prototyping and large-scale production needs, we are committed to delivering solutions that precisely align with your specifications.
