Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out with its versatility and cost-effectiveness compared to other advanced ceramics. It exhibits extraordinary electrical insulation, withstands high temperatures, and offers robust hardness, excellent wear resistance, and remarkable chemical stability, perfect for high-temperature and corrosive environments.
Our meticulous production process for alumina parts ranges from 75% to 99.8% purities. Each component is crafted with a dense body formed through dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications such as friction reduction, insulation enhancement, or assembly fitting, we offer secondary processes post-sintering including CNC machining, polishing, glazing, and metalizing to achieve superior performance.
We specialize in manufacturing a vast selection of alumina ceramic rings, encompassing tubes, rings, discs, rods, arms, and wire guides. Whether your requirements are for prototyping or extensive production runs, we guarantee a solution tailored to meet your exact needs with precision and reliability.
