Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) emerges as a titan in versatile applications, celebrated for its cost-effectiveness over other advanced ceramics. Renowned for high electrical insulation resistance, robust high-temperature endurance, and formidable hardness, alumina's wear resistance and chemical stability make it an exemplary choice for facing extreme temperatures and chemical attacks.
Proudly crafting alumina parts with purities from 75% to 99.8%, our ceramics form through diverse methods like dry pressing, hot pressing, ceramic injection molding, and ISO pressing for a dense body. We cater to specialized applications requiring reduced friction and enhanced insulation through secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing, to meet precise demands.
Our production repertoire includes a diverse range of alumina ceramic rings, extending to ceramic tubes, rings, discs, rods, arms, and wire guides. From prototype crafting to fulfilling high-volume demands, we are steadfast in providing solutions tailored to meet your exact specifications.
