Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) distinguishes itself with a broad array of applications, owing to its versatility and economic advantage over other advanced ceramics. Renowned for its exceptional electrical insulation, resistance to extreme temperatures, supreme hardness, wear resistance, and exemplary chemical stability, Alumina is the ideal choice for challenging high-temperature and corrosive environments.
Our state-of-the-art manufacturing facility crafts alumina parts with purities ranging from an impressive 75% to a near-perfect 99.8%. Utilizing cutting-edge techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we create dense ceramic bodies. For specialized needs requiring enhanced fitting, friction reduction, and superior insulation, we offer advanced secondary processes such as CNC machining, polishing, glazing, and metalizing post-sintering.
We excel in producing a diverse range of alumina ceramic products, including rings, tubes, discs, rods, arms, and wire guides, from prototypes to high-volume production. We are committed to delivering solutions precisely tailored to your specific needs.
