Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is extensively utilized due to its versatility and lower material cost compared to other advanced ceramics. Alumina boasts high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and robust chemical stability, making it an ideal material for high-temperature and chemically corrosive environments.
Our factory offers a variety of alumina purities ranging 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. To meet specific application needs such as fitting, friction reduction, and insulation enhancement, we provide a series of secondary processes post-sintering, including CNC machining, polishing, glazing, and metallizing.
We manufacture a wide array of alumina ceramic products, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether it's for prototyping or high-volume demands, we are confident in our ability to offer a solution that meets your needs.
