Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) distinguishes itself with its wide-ranging applications, attributed to its adaptability and economical advantage over other sophisticated ceramics. Alumina excels with superior electrical insulation, outstanding high-temperature resilience, formidable hardness, robust wear resistance, and exceptional chemical stability. This makes it perfect for applications demanding high temperature endurance and chemical corrosion resistance.
Our state-of-the-art facility manufactures alumina parts with purities spanning from 75% to an impressive 99.8%. Every ceramic component we offer is crafted with a dense structure through advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications needing enhanced fitting, reduced friction, and improved insulation, we perform secondary processes post-sintering like CNC machining, polishing, glazing, and metalizing.
We proudly produce a diverse range of alumina ceramic products, including tubes, rings, discs, rods, arms, and wire guides. Whether your project involves prototyping or requires high-volume production, we guarantee a solution perfectly aligned with your requirements.
