Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out for its remarkable versatility and cost-effectiveness compared to other advanced ceramics. This material is characterized by its high electrical insulation resistance, exceptional high-temperature endurance, impressive hardness, superb wear resistance, and steadfast chemical stability, making it the material of choice for applications subjected to high temperatures and corrosive environments.
Our expert facilities produce alumina parts ranging in purity from 75% to 99.8%. Each ceramic component boasts a robust, dense body crafted through techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications requiring enhanced fitting, friction reduction, and superior insulation, we offer post-sintering secondary processes, including precise CNC machining, polishing, glazing, and expert metalizing.
We expertly manufacture a wide range of alumina ceramic rings, encompassing tubes, rings, discs, rods, arms, and wire guides. Whether your needs are for prototyping or high-volume production, we assure a tailored solution to fulfill your demands with precision and efficiency.
