Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) offers extensive applications due to its versatility and lower material cost compared to other advanced ceramics. Alumina boasts high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and chemical stability, making it ideal for enduring high temperatures and chemical corrosion.
Our factory produces alumina parts with purities ranging from 75% to 99.8%. All ceramic parts we supply have a dense body formed via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To cater to special applications like fitting, reducing friction, and enhancing insulation, we provide secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We manufacture a broad array of alumina ceramic rings, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether for prototyping or high-volume demand, we are confident in delivering a solution that meets your needs.
