Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out for its adaptable nature and cost-effectiveness in comparison to other advanced ceramics. Its remarkable properties include high electrical insulation resistance, ability to withstand high temperatures, impressive hardness, excellent wear resistance, and chemical stability, making it an optimal choice for applications requiring endurance against extreme temperatures and chemical exposure.
Our state-of-the-art facility is adept at producing alumina parts featuring purities from 75% to an extraordinary 99.8%. The dense construction of our ceramic parts is achieved through advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet specific applications involving fitting, friction reduction, and insulation enhancement, we offer secondary processes after sintering, which encompass CNC machining, polishing, glazing, and metalizing.
We proudly manufacture an extensive selection of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Whether you're in the prototyping phase or scaling up to high-volume production, we have the expertise to deliver a solution tailored to meet your precise requirements.
