Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its diverse applications, attributed to its versatility and affordability compared to other advanced ceramics. Alumina showcases high electrical insulation resistance, excellent high-temperature endurance, remarkable hardness, wear resistance, and outstanding chemical stability-making it a preferred choice for withstanding high temperatures and chemical corrosion.
Our factory specializes in producing alumina parts with purities ranging from 75% to 99.8%. Each ceramic part we offer features a dense body created through methods such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To address special applications, such as fitting, reducing friction, and improving insulation, we provide secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing to enhance functionality.
We proudly manufacture an extensive range of alumina ceramic rings, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your needs are for prototyping or require high-volume production, our commitment is to deliver solutions tailored to your exact specifications.
