Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its versatility and cost-efficiency, standing out among advanced ceramics. Its exceptional electrical insulation, high-temperature resistance, superior hardness, wear resistance, and chemical stability make it indispensable in high-temperature and corrosive settings.
Our facility boasts the capability to fabricate alumina parts with purities from a robust 75% to an incredible 99.8%. Utilizing cutting-edge techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we create dense ceramic forms. For specialized purposes requiring precise fitting, reduced friction, and superior insulation, we offer advanced secondary processes including CNC machining, polishing, glazing, and metalizing post-sintering.
We take pride in offering a comprehensive range of alumina ceramic products, including rings, tubes, discs, rods, arms, and wire guides, fulfilling needs from prototyping to high-volume production. Our solutions are crafted to satisfy your specific demands.
