Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its versatility, offering a spectrum of applications owing to its cost-effectiveness relative to other advanced ceramics. It excels with high electrical insulation resistance, enduring high temperatures, impressive hardness, wear resistance, and chemical stability, making it ideal for environments demanding resilience against temperatures and chemical corrosion.
Our factory excels in producing alumina parts with purities stretching from 75% to an outstanding 99.8%. Each ceramic component we offer is robustly structured via advanced methods such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet specialized needs like fitting, reducing friction, and boosting insulation, we provide post-sintering secondary processes including CNC machining, polishing, glazing, and metalizing.
Our extensive production line includes a vast selection of alumina ceramic rings, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you're in the prototyping phase or require high-volume production, we are committed to delivering solutions tailored to your specific demands.
