Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its remarkable adaptability and cost-effectiveness compared to other advanced ceramics. Alumina excels in high electrical insulation resistance, outstanding high-temperature resistance, exceptional hardness, impressive wear resistance, and unparalleled chemical stability. This makes it a prime choice for applications enduring extreme temperatures and resisting chemical erosion.
At our state-of-the-art factory, we craft alumina parts boasting purities from 75% to 99.8%. Our ceramic parts are meticulously shaped through dry pressing, hot pressing, ceramic injection molding, and ISO pressing techniques. To address specialized applications such as fitting, friction reduction, and insulation enhancement, we offer secondary post-sintering processes including advanced CNC machining, polishing, glazing, and metalizing.
We proudly manufacture a diverse range of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Whether you require a prototype or a high-volume production run, we are equipped to deliver solutions tailored to meet your exact specifications.
