Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out for its broad spectrum of applications, courtesy of its adaptability and cost-effectiveness in comparison to other advanced ceramics. Its exceptional characteristics include superior electrical insulation resistance, formidable high-temperature endurance, remarkable hardness, outstanding wear resistance, and robust chemical stability, making it the quintessential choice for withstanding extreme temperatures and chemical corrosion.
Our factory is equipped to deliver alumina parts with purity levels spanning from 75% to an astonishing 99.8%. The ceramic parts we provide are crafted to perfection, utilizing techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet unique application requirements like fitting, friction reduction, and insulation enhancement, we offer additional post-sintering processes including CNC machining, polishing, glazing, and metalizing.
We specialize in the production of an extensive range of alumina ceramic rings, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you are in need of prototyping solutions or high-volume production, we assure you of a tailored solution that seamlessly aligns with your specific demands.
