Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its incredible versatility and cost-effectiveness compared to other advanced ceramics. It shines with high electrical insulation resistance, exceptional high-temperature tolerance, robust hardness, wear resistance, and steadfast chemical stability, making it the perfect choice for demanding environments characterized by extreme temperatures and corrosive conditions.
Our state-of-the-art facility crafts alumina parts with purities ranging from 75% to a remarkable 99.8%. Each ceramic part is meticulously shaped using techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized purposes like fitting, friction reduction, and insulation enhancement, we offer advanced secondary processes post-sintering, including CNC precision machining, polishing, glazing, and expert metalizing.
We specialize in producing a diverse range of alumina ceramic rings, such as ceramic tubes, rings, discs, rods, arms, and wire guides. From prototypes to high-volume production, we are dedicated to providing custom solutions that precisely meet your requirements.
