Description of Alumina Ceramic Parts
Aluminum Oxide (Alumina) is renowned for its versatility and cost-efficiency compared to other advanced ceramics. With superior electrical insulation resistance, high-temperature endurance, impressive hardness, wear resistance, and excellent chemical stability, Alumina stands as an ideal material for high-temperature and chemically corrosive environments.
Our factory offers a variety of alumina purities ranging from 75% to 99.8%. Every ceramic part we supply is densified through dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For unique applications requiring reduced friction and increased insulation, we provide secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We manufacture a comprehensive range of alumina ceramic products, including tubes, rings, discs, rods, arms, and wire guides. Whether you need a prototype or high-volume production, we are equipped to deliver the perfect solution for your needs.
