Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is celebrated for its wide-ranging applications thanks to its adaptability and cost-efficiency compared to other advanced ceramics. Renowned for its superb electrical insulation, stellar high-temperature tolerance, remarkable hardness, wear resistance, and exceptional chemical stability, Alumina is the optimum choice for high-temperature and corrosive settings.
Our advanced manufacturing facility produces alumina parts with purities from a sturdy 75% to an almost flawless 99.8%. Utilizing cutting-edge techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we form dense ceramic bodies. For specialized applications necessitating enhanced fitting, friction reduction, and superior insulation, we offer an array of secondary processes, including CNC machining, polishing, glazing, and metalizing post-sintering.
We specialize in a diverse range of alumina ceramic products, including rings, tubes, discs, rods, arms, and wire guides, supporting both prototyping and high-volume production. We provide solutions crafted to your exact requirements with confidence.
