Comprehensive Description of Our Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out due to its versatility and cost-effectiveness compared to other advanced ceramics. With high electrical insulation resistance, superior high-temperature resistance, remarkable hardness, wear resistance, and excellent chemical stability, alumina is the ideal material for enduring high temperatures and chemical corrosion.
Our factory offers alumina in purities ranging from 75% to 99.8%. All supplied ceramic parts are forged for density through methods like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet specialized applications requiring reduced friction and increased insulation, we provide secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We specialize in manufacturing an array of alumina ceramic rings and components, such as ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you need a prototype or high-volume production, we are committed to delivering the ideal solution to meet your needs.
