Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its versatile applications and cost-effectiveness compared to other advanced ceramics. Excel in environments requiring high electrical insulation resistance, high-temperature endurance, robust hardness, wear resistance, and impressive chemical stability, ensuring performance under extreme heat and corrosive conditions.
We craft alumina parts with purities from 75% to a stellar 99.8%. Each ceramic piece is expertly manufactured with a dense body formed through advanced techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. Post-sintering, we offer tailored secondary processes such as CNC machining, polishing, glazing, and metalizing to meet specialized needs like fitting, reducing friction, and enhancing insulation.
We specialize in a diverse selection of alumina ceramic components including tubes, rings, discs, rods, arms, and wire guides. From initial prototyping to high-volume requests, we ensure solutions that precisely match your requirements.
