Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) boasts extensive applications due to its versatility and cost efficiency compared to other advanced ceramics. Alumina provides high electrical insulation resistance, high-temperature endurance, strong hardness, wear resistance, and outstanding chemical stability, making it an ideal material to withstand high temperatures and chemical corrosion.
Our factory manufactures a selection of alumina ranging from 75% to 99.8% purity. All ceramic parts we supply feature a dense body created via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To meet special application needs such as fitting adjustments, friction reduction, and insulation enhancement, we offer secondary processes post-sintering, including CNC machining, polishing, glazing, and metallizing.
We specialize in a wide range of alumina ceramic rings, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether for prototyping or high-volume demand, we are confident in delivering a desirable solution.
