Introduction to Alumina Ceramic Components
Aluminum oxide (Alumina) is renowned for its adaptability and cost-effectiveness compared to other advanced ceramics. It excels with its high electrical insulation resistance, superior temperature tolerance, exceptional hardness, wear resistance, and chemical stability. This makes it ideal for demanding high-temperature and corrosive chemical environments.
Our state-of-the-art manufacturing facility produces alumina parts with purities spanning from 75% to 99.8%, ensuring a dense body structure through techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications such as fitting, reducing friction, and enhancing insulation, we offer post-sintering secondary processes including CNC machining, polishing, glazing, and metalizing.
We expertly manufacture a comprehensive range of alumina ceramic rings, encompassing tubes, rings, discs, rods, arms, and wire guides. Whether your needs involve prototyping or large-scale production, we are committed to delivering tailor-made solutions that exceed your expectations.
