Description of Alumina Ceramic Parts
Aluminum oxide, commonly known as Alumina, presents remarkable versatility and cost-effectiveness compared to other high-tech ceramics. With excellent electrical insulation, impressive resistance to high temperatures, outstanding hardness, and strong wear and chemical resistance, alumina is superbly suited for tolerating extreme heat and chemical exposure.
At our facility, we offer alumina components with purity levels spanning from 75% to 99.8%. Utilizing advanced techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we ensure that every ceramic part is densely constructed. For specialized applications that require enhanced fitting, friction reduction, or improved insulation, we provide secondary post-sintering processes such as CNC machining, polishing, glazing, and metalizing.
Our production line includes a wide spectrum of alumina ceramic products-such as tubes, rings, discs, rods, arms, and wire guides. Whether you need a prototype or require large-scale production, we are equipped to deliver solutions tailored to your specific requirements.
