Description of Alumina Ceramic Parts
Aluminum oxide (Alumina), a versatile material, stands out for its affordability compared to other advanced ceramics. Its remarkable properties include high electrical insulation resistance, exceptional high-temperature endurance, robust hardness, wear resistance, and outstanding chemical stability, making it the optimal choice for applications enduring extreme temperatures and chemical exposure.
Our factory is adept at producing alumina parts with purities ranging from 75% to 99.8%. Each piece undergoes precise formation through methods such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications that require fitting, friction reduction, and insulation enhancement, we offer post-sintering secondary processes including CNC machining, polishing, glazing, and metalizing.
We specialize in manufacturing a diverse range of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Whether for prototyping or satisfying high-volume demands, we are dedicated to delivering solutions that precisely align with your requirements.
