Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) shines with its wide-ranging applications due to its adaptability and economical nature compared to other high-performance ceramics. Renowned for its superior electrical insulation, exceptional high-temperature resistance, outstanding hardness, wear resistance, and excellent chemical stability, Alumina is the perfect choice for high-temperature and corrosive conditions.
Our advanced manufacturing facility creates alumina parts with purities from a sturdy 75% up to an almost flawless 99.8%. We utilize cutting-edge methods like dry pressing, hot pressing, ceramic injection molding, and ISO pressing to form dense ceramic structures. For applications demanding enhanced fitting, reduced friction, and superior insulation, we provide additional processes, including CNC machining, polishing, glazing, and metalizing after sintering.
We excel in producing a broad array of alumina ceramic products such as rings, tubes, discs, rods, arms, and wire guides, from prototypes to large-scale production. We deliver bespoke solutions to meet your precise needs with confidence.
