Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is an essential industrial material, revered for its broad array of applications due to its impressive versatility and cost-effectiveness over other sophisticated ceramics. Distinguished by exceptional electrical insulation, high resistance to extreme temperatures, formidable hardness, resilient wear resistance, and unparalleled chemical stability, Alumina triumphs in both high-temperature and corrosive conditions.
Within our advanced manufacturing facility, we craft alumina parts with remarkable purities ranging from a robust 75% to a near-flawless 99.8%. Utilizing cutting-edge methods such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we forge dense ceramic structures. For applications demanding heightened fit, friction minimization, and superior insulation, our secondary processes include CNC machining, polishing, glazing, and metalizing post-sintering, ensuring exceptional quality.
Our expertise spans a diverse range of alumina ceramic products, including rings, tubes, discs, rods, arms, and wire guides, efficiently catering from initial prototyping to full-scale production. We stand ready to deliver solutions that precisely align with your unique needs.
