Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is your gateway to versatile, high-performance solutions. Its cost-effectiveness triumphs over other advanced ceramics, offering unparalleled electrical insulation, resistance to high temperatures, and formidable hardness. These properties make it the prime choice for withstanding severe heat and corrosive environments, proving invaluable across diverse industries.
Our state-of-the-art factory produces premium alumina parts with purities ranging from 75% to 99.8%. Each piece is crafted with precision using dry pressing, hot pressing, ceramic injection molding, and ISO pressing techniques. We extend our expertise with post-sintering secondary processes, including CNC machining, polishing, glazing, and metalizing, to tailor solutions for specific needs such as enhancing fit, reducing friction, and boosting insulation.
We offer an extensive selection of alumina ceramic rings, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you're prototyping or fulfilling high-volume production demands, we are equipped to deliver solutions that precisely match your specifications.
