The description of alumina ceramic parts
Aluminum oxide (Alumina) has extensive applications due to its versatility and lower material cost compared to other advanced ceramics. Alumina offers exceptional electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and robust chemical stability. These properties make it an ideal choice for enduring high temperatures and chemical corrosion.
Our factory produces a selection of alumina purity ranging from 75% to 99.8%. All ceramic parts we supply exhibit a dense body, utilizing processes such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To cater to special applications requiring enhanced fitting, reduced friction, and increased insulation, we offer a series of secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We manufacture a wide array of alumina ceramic rings, including ceramic tubes, ceramic rings, ceramic discs, ceramic rods, ceramic arms, and ceramic wire guides. Whether it's a prototyping case or a demand for high-volume production, we are confident in delivering a solution that meets your needs.
