The description of alumina ceramic parts
Aluminum oxide (Alumina) is widely used due to its versatility and cost-effectiveness compared to other advanced ceramics. Alumina boasts high electrical insulation resistance, exceptional high-temperature resistance, impressive hardness, superior wear resistance, and excellent chemical stability, making it an ideal material for high-temperature and chemical corrosion environments.
Our factory offers a variety of alumina purities ranging from 75% to 99.8%. All supplied ceramic parts feature a dense body formed through methods such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To cater to specific applications like fitting adjustments, friction reduction, and insulation enhancement, we provide secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We manufacture a diverse array of alumina ceramic components, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you need prototyping or high-volume production, we are confident in our ability to deliver the perfect solution to meet your needs.
