Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out as a cost-effective ceramic material offering unparalleled versatility. Renowned for its superior electrical insulation, resistance to high temperatures, exceptional hardness, wear resistance, and stable chemical properties, alumina is the go-to choice for conditions requiring durability against extreme temperatures and corrosive chemicals.
At our state-of-the-art facility, we produce alumina parts with purities between 75% and 99.8%. Our ceramic components boast a robust, dense body achieved through advanced techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications-whether it's reducing friction, enhancing insulation, or adapting to unique fits-we offer post-sintering processes such as CNC machining, polishing, glazing, and metalizing, delivering tailored solutions for every need.
Specializing in a wide spectrum of alumina ceramic rings, our expertise extends to the production of tubes, discs, rods, arms, and wire guides. Whether your needs are for prototypes or high-volume production, rest assured, we possess the capability and confidence to provide solutions that precisely match your requirements.
