Description of Alumina Ceramic Components
Aluminum oxide (Alumina) is widely valued for its versatility and cost-effectiveness compared to other advanced ceramics. Alumina provides outstanding electrical insulation resistance, high-temperature endurance, exceptional hardness, wear resistance, and robust chemical stability, making it ideal for high-temperature and corrosive environments.
Our factory offers a range of alumina purities from 75% to 99.8%. Each ceramic part is manufactured with a dense body using dry pressing, hot pressing, ceramic injection molding, and ISO pressing techniques. To meet specialized application needs such as reduced friction and enhanced insulation, we perform secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We produce a comprehensive array of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Whether it's a prototype or a high-volume order, we are confident in providing the perfect solution for your needs.
