Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands unrivaled for its incredible versatility and cost-effectiveness, offering unparalleled electrical insulation resistance, outstanding high-temperature endurance, exceptional hardness, superior wear resistance, and extraordinary chemical stability. It is the ideal choice to withstand extreme temperatures and harsh chemical environments.
Our cutting-edge facility manufactures alumina parts with remarkable purity levels ranging from 75% to an impressive 99.8%. Each ceramic component is meticulously crafted using advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For tailored applications requiring precise fitting, reduced friction, and optimized insulation, we provide post-sintering secondary processes including CNC machining, polishing, glazing, and metalizing.
We take pride in producing a vast array of alumina ceramic components, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your project demands prototyping or large-scale production, we have the expertise to provide a solution finely tuned to your specific needs.
