Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is celebrated for its remarkable versatility and cost-effectiveness, offering high electrical insulation, resistance to extreme temperatures, exceptional hardness, wear resistance, and chemical stability. This makes it ideal for applications requiring durability against high temperatures and chemical corrosion.
Our factory excels in producing alumina parts with purities from 75% to 99.8%. We use advanced methods like dry pressing, hot pressing, ceramic injection molding, and ISO pressing to ensure a dense body for all ceramic parts. For specialized needs such as fitting, friction reduction, and insulation enhancement, we offer post-sintering processes like CNC machining, polishing, glazing, and metalizing.
We specialize in manufacturing a diverse range of alumina ceramic components, including tubes, rings, discs, rods, arms, and wire guides. Whether for prototypes or large-scale production, we guarantee solutions that align with your requirements.
