Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out for its remarkable versatility and cost-efficiency compared to other advanced ceramics. With its superior properties, including high electrical insulation resistance, exceptional high-temperature endurance, impressive hardness, robust wear resistance, and outstanding chemical stability, alumina is an ideal choice for applications involving extreme temperatures and chemical exposure.
Our state-of-the-art facility specializes in producing alumina parts with purities ranging from an impressive 75% to an outstanding 99.8%. All our ceramic components boast a dense structure achieved through advanced methods like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications requiring enhanced functionality such as fitting, friction reduction, and improved insulation, we offer secondary post-sintering processes including CNC machining, polishing, glazing, and metalizing to elevate performance.
We pride ourselves on manufacturing an extensive range of alumina ceramic rings, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your need is for prototype development or large-scale production, rest assured that we are committed to delivering a tailored solution that perfectly aligns with your specific requirements.
