Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands out as a versatile and economically advantageous material among high-performance ceramics. Revered for its exceptional electrical insulation resistance, superb high-temperature durability, incredible hardness, wear resistance, and superior chemical stability, alumina is the premier choice for challenging environments resisting extreme heat and corrosive chemicals.
Within our state-of-the-art facility, we produce alumina components of extraordinary purity, spanning from 75% to an extraordinary 99.8%. Every ceramic unit is precisely fabricated using cutting-edge techniques including dry pressing, hot pressing, ceramic injection molding, and ISO pressing. Addressing specialized needs for fitting, friction reduction, and optimal insulation, we offer advanced post-sintering processes such as CNC machining, polishing, glazing, and metalizing.
We are proud to produce an extensive range of alumina ceramic components, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your project involves prototyping or mass production, we deliver unmatched expertise in customizing solutions to meet your exact requirements.
