Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is celebrated for its remarkable versatility and cost-effectiveness in the realm of advanced ceramics. With its outstanding electrical insulation resistance, superior high-temperature resilience, impressive hardness, wear resistance, and chemical stability, it stands as the ideal choice for enduring extreme temperatures and resisting chemical corrosion with ease.
Our state-of-the-art facility excels in producing alumina parts with purities ranging from 75% to a remarkable 99.8%. Each ceramic component boasts a dense body meticulously crafted through innovative techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To address distinct application needs like fitting, friction reduction, and enhanced insulation, we deliver precise post-sintering secondary processes, including CNC machining, polishing, glazing, and metalizing.
We proficiently manufacture a diverse array of alumina ceramic components, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your requirements entail prototyping or high-volume production, we are fully equipped and confident in providing solutions that flawlessly align with your needs.
