Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is celebrated for its diverse applications due to its versatility and affordability when compared to other high-performance ceramics. Renowned for its extraordinary electrical insulation, excellent high-temperature resistance, unmatched hardness, wear resistance, and superior chemical stability, Alumina is perfectly suited for high-temperature and corrosive environments.
Our advanced manufacturing capabilities enable the production of alumina parts with purities from a solid 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 ceramic bodies. For specialized applications necessitating enhanced fitting, friction reduction, and exceptional insulation, we offer an array of secondary processes, including CNC machining, polishing, glazing, and post-sintering metalizing.
We excel in producing a vast range of alumina ceramic products, including rings, tubes, discs, rods, arms, and wire guides, serving everything from initial prototype stages to large-scale production. Trust us to deliver customized solutions perfectly aligned with your demanding standards.
