Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is widely used due to its adaptability and cost-effectiveness compared to other advanced ceramics. Alumina boasts high electrical insulation, high-temperature resistance, remarkable hardness, wear resistance, and robust chemical stability, ideal for enduring high temperatures and chemical corrosion.
Our factory produces a variety of alumina purities ranging from 75% to 99.8%. All ceramic parts we supply feature dense bodies formed by dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet special applications for fitting, reducing friction, and increasing insulation, we offer various secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We manufacture an extensive range of alumina ceramic products, including tubes, rings, discs, rods, arms, and wire guides. Whether for prototyping or high-volume production, we are committed to delivering the perfect solution for your needs.
