Detailed Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) boasts extensive applications due to its versatility and cost-effectiveness compared to other advanced ceramics. Alumina delivers high electrical insulation resistance, exceptional high-temperature resistance, robust hardness, wear resistance, and impressive chemical stability, rendering it an ideal material for withstanding extreme temperatures and chemical corrosion.
Our factory produces a variety of alumina purity levels from 75% to 99.8%. All ceramic parts we supply feature a dense body achieved through dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications requiring reduced friction and increased insulation, we offer a series of secondary processes post-sintering, including CNC machining, polishing, glazing, and metallizing.
We manufacture an extensive array of alumina ceramic components, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you're in need of prototyping or high-volume production, we are confident in our ability to deliver the perfect solution for your needs.
