Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is celebrated for its diverse applications and affordability, standing out among advanced ceramics. Renowned for its superior electrical insulation, resistance to high temperatures, outstanding hardness, wear resistance, and unparalleled chemical stability, Alumina is the perfect choice for challenging high-temperature and corrosive environments.
Our advanced manufacturing facility produces high-quality alumina parts with purities ranging from a robust 75% to an exceptional 99.8%. Utilizing cutting-edge techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we create dense and enduring ceramic bodies. For specialized applications demanding superior fitting, friction reduction, and exceptional insulation, we provide a range of secondary processes, including CNC machining, polishing, glazing, and metalizing post-sintering.
Specializing in a vast array of alumina ceramic products, including rings, tubes, discs, rods, arms, and wire guides, we offer solutions from prototyping to large-scale production, tailored precisely to meet your specific needs.
