Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is celebrated for its remarkable versatility and cost-effectiveness compared to other advanced ceramics. It excels in providing high electrical insulation resistance, tolerance to high temperatures, exceptional hardness, wear resistance, and robust chemical stability, making it the top choice for scenarios involving extreme heat and chemical exposure.
Our factory specializes in crafting alumina parts with purities ranging from 75% to an impressive 99.8%. We offer a robust selection of ceramic parts, meticulously formed through processes like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications, such as enhancing fittings, reducing friction, and maximizing insulation, we employ various secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing, ensuring tailored solutions to meet all your requirements.
We take pride in manufacturing an extensive range of alumina ceramic rings, as well as ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you're seeking prototype solutions or high-volume production, we are dedicated to delivering products that align perfectly with your specifications and demands.
