Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its wide-ranging applications, stemming from its adaptability and reduced material cost compared to other advanced ceramics. Alumina stands out with its high electrical insulation resistance, exceptional high-temperature resistance, robust hardness, superior wear resistance, and outstanding chemical stability. This makes it a preferred choice for withstanding extreme temperatures and chemical corrosion.
Our factory specializes in producing alumina parts with purity levels from 75% up to an impressive 99.8%. All ceramic components provided are meticulously crafted with a dense body through processes like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To address unique applications such as fitting, friction reduction, or insulation enhancement, we offer secondary post-sintering treatments that include CNC machining, polishing, glazing, and metalizing.
We expertly manufacture a diverse range of alumina ceramic products, such as ceramic tubes, rings, discs, rods, arms, and wire guides. Whether you require prototypes or have high-volume demands, we are fully equipped to deliver solutions tailored to meet your exact specifications.
