Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is distinguished by its exceptional versatility, offering a cost-effective alternative to other advanced ceramics. Alumina stands out with its superior electrical insulation resistance, exceptional durability against high temperatures, robust hardness, wear resistance, and remarkable chemical stability, making it the go-to material for environments exposed to extreme temperatures and chemical erosion.
Our state-of-the-art production facility offers alumina parts with a purity spectrum ranging from 75% to a pristine 99.8%. Each piece is crafted to perfection using advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing, resulting in a flawlessly dense body. For specialized applications such as friction reduction and insulation enhancement, we offer meticulous secondary processes post-sintering, which include precision CNC machining, polishing, glazing, and expert metalizing.
Our manufacturing capabilities encompass a diverse range of alumina ceramic items, including tubes, rings, discs, rods, arms, and wire guides. Whether your project demands prototyping or large-scale production, we are committed to providing solutions tailored to meet your specific requirements with unwavering confidence.
