Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is celebrated for its versatility and cost-efficiency compared to other advanced ceramics. Known for its outstanding electrical insulation resistance, high-temperature endurance, and robust hardness, Alumina is also highly resistant to wear and chemical corrosion, making it perfect for applications involving extreme conditions.
Our facility produces alumina components with purities ranging from 75% to a remarkable 99.8%. These ceramic parts feature a dense structure achieved through dry pressing, hot pressing, ceramic injection molding, and ISO pressing techniques. For specialized applications like fitting, reducing friction, and boosting insulation, we offer post-sintering processes including CNC machining, polishing, glazing, and metalizing.
We excel in manufacturing a diverse range of alumina ceramic products, such as ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you're looking for prototypes or high-volume production, we are fully equipped to meet your specific requirements.
