Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) unlocks extensive applications thanks to its unmatched versatility and cost-effectiveness when compared to other advanced ceramics. Revel in its superior electrical insulation, resistance to high temperatures, incredible hardness, wear resistance, and chemical stability, making it ideal for thriving in high-temperature and corrosive environments.
Our factory masterfully crafts alumina parts in purities ranging from 75% to an exceptional 99.8%. Every piece features a robust dense body created through state-of-the-art techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized needs, we offer post-sintering secondary processes, including meticulous CNC machining, exquisite polishing, glazing, and metalizing, to enhance fitting, reduce friction, and bolster insulation.
We expertly manufacture a wide spectrum of alumina ceramic rings, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. From initial prototyping to fulfilling high-volume demands, we assure a tailored solution that aligns perfectly with your specifications.
