Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is a standout material renowned for its diverse applications, thanks to its versatility and competitive cost compared to other high-end ceramics. With unmatched electrical insulation, exceptional high-temperature resistance, superior hardness, and wear resistance, Alumina thrives in both high-temperature and corrosive environments, making it an ideal choice for demanding applications.
Our cutting-edge manufacturing facility creates alumina parts with purities ranging from a robust 75% to an unparalleled 99.8%. Utilizing advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we craft dense ceramic bodies. For specialized applications demanding tight fitting, friction reduction, and superior insulation, we offer a comprehensive range of secondary processes including CNC machining, polishing, glazing, and metalizing post-sintering, ensuring tailored solutions for your needs.
We excel in producing a vast array of alumina ceramic products such as rings, tubes, discs, rods, arms, and wire guides. Whether you require prototyping or large-scale production, we deliver bespoke solutions meticulously tailored to meet your unique specifications.
