Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) shines with its versatile utility, being exceptionally cost-effective amidst advanced ceramics. Famous for unmatched electrical insulation, formidable high-temperature resistance, impressive hardness, wear durability, and chemical stability, Alumina excels in extreme environments.
Our cutting-edge manufacturing techniques ensure alumina parts with purities from 75% to an impeccable 99.8%. Using methods like dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we create dense, high-quality ceramic bodies. Additionally, our secondary processes, including CNC machining, polishing, glazing, and metalizing, cater to specialized applications demanding high fit, reduced friction, and superior insulation.
We excel in producing a wide array of alumina ceramic products - from rings, tubes, discs, rods, arms, to wire guides. Whether you need prototypes or high-volume production, we offer bespoke solutions perfectly aligned with your unique specifications.
