The description of alumina ceramic parts
Aluminum oxide (Alumina) is highly versatile and cost-efficient compared to other advanced ceramics. It offers superior electrical insulation resistance, high-temperature tolerance, exceptional hardness, wear resistance, and chemical stability, making it ideal for enduring high temperatures and chemical corrosion.
Our factory produces alumina ceramics with purities ranging from 75% to 99.8%. All ceramic parts are crafted with dense bodies via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet specialized fitting, friction reduction, and insulation needs, we offer a range of secondary processes post-sintering, including CNC machining, polishing, glazing, and metallizing.
We manufacture a broad array of alumina ceramic products, such as tubes, rings, discs, rods, arms, and wire guides. Whether for prototyping or high-volume production, we are confident in providing the perfect solution for your needs.
