Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) distinguishes itself with unmatched versatility and competitive cost-efficiency over other advanced ceramics. Known for excellent electrical insulation, robust high-temperature resilience, superior hardness, exceptional wear resistance, and immense chemical stability, Alumina is perfectly suited for challenging environments requiring resistance to heat and chemical corrosion.
Our factory excels in producing alumina components with purities ranging from 75% to an impressive 99.8%. Every ceramic part is crafted with a dense structure through innovative techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications that necessitate reduced friction, tailored fitting, and improved insulation, we offer secondary processing post-sintering, including advanced CNC machining, precision polishing, enhanced glazing, and comprehensive metalizing.
We proudly manufacture a diverse range of alumina ceramic products including ceramic tubes, rings, discs, rods, arms, and sophisticated wire guides. Whether for initial prototypes or mass production, we are dedicated to delivering solutions that precisely align with your specific requirements.
