Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is distinguished by its remarkable versatility and cost-efficiency, making it superior among advanced ceramics. Its outstanding electrical insulation, high-temperature resistance, formidable hardness, and superior wear and chemical resistance make it the ultimate material for enduring extreme conditions and chemical exposure.
Our state-of-the-art facility excels in producing alumina parts with purities from 75% to an impressive 99.8%. Each part boasts a dense structure, crafted through techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. We ensure precise secondary processing post-sintering, including CNC machining, polishing, glazing, and metalizing to suit specific application needs like fitting, reducing friction, and enhancing insulation.
We specialize in manufacturing a vast array of alumina ceramic components such as ceramic tubes, rings, discs, rods, arms, and wire guides. From prototyping to large-scale production, we are fully equipped and committed to delivering solutions that perfectly align with your specifications.
