Description of Alumina Ceramic Parts: A detailed overview of our superior alumina ceramic components.
Aluminum oxide (Alumina) boasts extensive applications due to its versatility and cost-effectiveness. With high electrical insulation resistance, heat resistance, hardness, wear resistance, and chemical stability, alumina is the material of choice for high-temperature and chemically corrosive environments.
Our factory offers alumina with purities ranging from 75% to 99.8%. The ceramic parts we provide are dense, formed using dry pressing, hot pressing, ceramic injection molding, and ISO pressing. We offer secondary processes post-sintering, such as CNC machining, polishing, glazing, and metalizing, to cater to special applications, reduce friction, and enhance insulation.
We manufacture a diverse range of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Whether for prototyping or high-volume demands, we are confident in delivering a solution that meets your needs.
