Description of Alumina Ceramic Parts
Alumina (Aluminum oxide) stands out for its versatility and cost-effectiveness compared to other advanced ceramics. It offers exceptional electrical insulation, high temperature endurance, impressive hardness, wear resistance, and chemical stability. These traits make it perfect for environments requiring high-temperature resilience and resistance to chemical corrosion.
Our factory excels in producing alumina parts with pure compositions ranging from 75% to a remarkable 99.8%. We ensure each piece has a dense body through techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To address specialized applications such as fittings, friction reduction, and insulation enhancement, we offer post-sintering processes including CNC machining, polishing, glazing, and metalizing.
We manufacture a diverse range of alumina ceramic components, such as tubes, rings, discs, rods, arms, and wire guides. From prototype to high-volume production, we are dedicated to providing solutions tailored to your specific requirements.
