Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) distinguishes itself with unparalleled versatility and cost-efficiency among advanced ceramics. Its exceptional properties of electrical insulation, resistance to high temperatures, superior hardness, wear resistance, and chemical stability make it the material of choice for high-temperature and corrosive environments.
Our state-of-the-art manufacturing facility produces alumina parts with purities from a robust 75% up to a near-perfect 99.8%, using advanced techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing to craft dense ceramic bodies. For specialized applications demanding enhanced fitting, reduced friction, and superior insulation, our suite of secondary processes includes CNC machining, polishing, glazing, and post-sintering metalizing, offering a comprehensive approach.
We excel in a broad array of alumina ceramic products, from rings and tubes to discs, rods, arms, and wire guides. Catering to needs from prototyping through to high-volume production, we deliver solutions precisely tailored to meet your specific requirements.
