Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its extensive applications, thanks to its remarkable versatility and cost-effectiveness compared to other advanced ceramics. Alumina is celebrated for its high electrical insulation resistance, impressive high-temperature resistance, exceptional hardness, superior wear resistance, and outstanding chemical stability. These attributes render it ideal for applications enduring extreme temperatures and aggressive chemical environments.
In our state-of-the-art factory, we produce alumina parts with purities ranging from 75% to an exceptional 99.8%. Every ceramic part we supply is meticulously densified using advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet the demands of unique applications, such as fitting, reducing friction, and enhancing insulation, we offer secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
Our production line boasts a broad array of alumina ceramic components, including tubes, rings, discs, rods, arms, and wire guides. Whether your needs are for prototyping or high-volume demands, we pride ourselves on delivering solutions that precisely meet your specifications and requirements.
