Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out with its multifaceted applications attributed to its versatility and cost-effectiveness compared to other advanced ceramics. Known for its exceptional electrical insulation, high-temperature resistance, superior hardness, wear resistance, and outstanding chemical stability, Alumina is ideal for high-temperature and corrosive environments.
Our manufacturing facility produces alumina parts with purities ranging from a robust 75% to a near-perfect 99.8%. We employ state-of-the-art techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing to create dense ceramic bodies. For specialized applications requiring enhanced fitting, friction reduction, and superior insulation, we offer a suite of secondary processes, including CNC machining, polishing, glazing, and metalizing post-sintering.
We specialize in a wide spectrum of alumina ceramic products, including rings, tubes, discs, rods, arms, and wire guides, catering from prototyping to high-volume production. We confidently deliver solutions tailored to your specific requirements.
