Description of Alumina Ceramic Parts
Aluminum oxide, commonly known as Alumina, is renowned for its extensive applications thanks to its incredible versatility and cost-effectiveness compared to other advanced ceramics. It offers exceptional electrical insulation resistance, withstands high temperatures, provides robust hardness along with superior wear resistance, and maintains excellent chemical stability, making it the perfect choice for applications enduring high heat and chemical exposure.
In our state-of-the-art facilities, we craft alumina parts in purities ranging from 75% to an outstanding 99.8%. Each ceramic component sports a dense body structure achieved through advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For unique applications requiring fitting, friction reduction, or insulation enhancement, we offer post-sintering secondary processes, including CNC machining, polishing, glazing, and metalizing.
We proudly produce an extensive range of alumina ceramic rings, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your needs are for initial prototyping or large-scale production, we promise a solution that is expertly tailored to your specifications.
