Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) distinguishes itself through its diverse applications, thanks to its remarkable versatility and cost-effectiveness when compared to other advanced ceramics. Renowned for its exceptional electrical insulation, ability to withstand high temperatures, superior hardness, resistance to wear, and exemplary chemical stability, Alumina is the material of choice for challenging high-temperature and corrosive environments.
Our cutting-edge manufacturing facility crafts alumina parts with purity levels spanning from an impressive 75% to a near-perfect 99.8%. We utilize advanced methods like dry pressing, hot pressing, ceramic injection molding, and ISO pressing to forge dense ceramic bodies. For specialized needs requiring enhanced fitting, friction reduction, and superior insulation, we provide an array of secondary processes, such as CNC machining, precise polishing, glazing, and meticulous metalizing after sintering.
Our expertise lies in a vast array of alumina ceramic products, including rings, tubes, discs, rods, arms, and wire guides, supporting everything from prototyping to high-volume production. We confidently offer solutions meticulously customized to fulfill your unique specifications.
