Description of Alumina Ceramic Parts
Alumina (Aluminum Oxide) is highly versatile and cost-effective compared to other advanced ceramics. It offers high electrical insulation, resistance to high temperatures, exceptional hardness, wear resistance, and chemical stability, making it ideal for withstanding high temperatures and chemical corrosion.
Our factory produces alumina with purities ranging from 75% to 99.8%. All ceramic parts feature a dense body created through dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications, we offer secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing, to enhance fitting, reduce friction, and increase insulation.
We manufacture a diverse array of alumina ceramic products such as ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you need prototyping or high-volume production, we are confident in providing you with an ideal solution.
