Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is celebrated for its exceptional adaptability, making it a cost-effective choice among advanced ceramics. With superior high electrical insulation resistance, it thrives under extreme temperatures, offering excellent hardness, wear resistance, and chemical stability. Alumina stands as the ideal solution for challenging high-temperature and corrosive environments.
Produced in our cutting-edge facility, our alumina parts boast impressive purity levels ranging from 75% to a remarkable 99.8%. Each piece is meticulously crafted through advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To cater to specialized applications demanding optimal fit, reduced friction, and enhanced insulation, we offer post-sintering secondary processes including CNC machining, polishing, glazing, and metalizing.
We are proud to offer a diverse array of alumina ceramic components, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you're in need of prototyping or large-scale production, our expertise ensures a solution meticulously tailored to meet your precise specifications.
