Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is the go-to choice for numerous applications due to its unmatched versatility and cost efficiency compared to other advanced ceramics. Alumina is lauded for its exceptional electrical insulation resistance, ability to withstand high temperatures, impressive hardness, wear resistance, and robust chemical stability, making it perfect for high-temperature and chemically corrosive environments.
Our factory proudly produces alumina parts with purities ranging from 75% to 99.8%. Each ceramic part delivers a dense body formed through advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet specialized needs like fitting, reducing friction, and improving insulation, we offer secondary post-sintering processes, including CNC machining, precision polishing, glazing, and metalizing.
We expertly craft an extensive range of alumina ceramic rings, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether for prototyping or high-volume production, our solutions are tailored to exceed your expectations.
