Description of Alumina Ceramic Parts
Alumina, or Aluminum Oxide, stands out with its extraordinary versatility and cost-effectiveness compared to other advanced ceramics. Its superior electrical insulation, extreme temperature and wear resistance, robust hardness, and remarkable chemical stability make it ideal for tackling high-temperature environments and corrosive conditions.
At our cutting-edge facility, we produce alumina parts with purity levels from 75% to a near-perfect 99.8%. We offer an impressive range of forming techniques including dry pressing, hot pressing, ceramic injection molding, and ISO pressing to ensure a dense ceramic body. For specialized applications such as fitting, friction reduction, and insulation enhancement, we provide post-sintering secondary processes, including CNC machining, polishing, glazing, and metalizing to meet your unique requirements.
Our expansive production capabilities include a vast selection of alumina ceramic products such as tubes, rings, discs, rods, arms, and wire guides. Whether you require a prototype or a large-scale production run, we have the expertise and confidence to deliver solutions tailored to your specifications and demands.
