Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its extraordinary versatility and economical advantage over other advanced ceramics. Its superior electrical insulation resistance, high-temperature endurance, formidable hardness, wear resistance, and chemical stability make it the premier choice for enduring high temperatures and resisting chemical corrosion.
Our state-of-the-art facility excels in producing alumina parts with purities from 75% up to a remarkable 99.8%. Each ceramic component is crafted with a dense body using advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To fulfill unique application needs for fitting, reducing friction, and enhancing insulation, we offer precise secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We specialize in manufacturing a comprehensive array of alumina ceramic components, including ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your need is for prototyping or high-volume production, we possess the capabilities and confidence to deliver solutions that precisely meet your demands.
