Description of Alumina Ceramic Parts
Our Aluminum oxide (Alumina) is versatile and cost-effective, setting a standard in advanced ceramics. With exceptional high electrical insulation resistance, outstanding high-temperature endurance, impressive hardness, unparalleled wear resistance, and strong chemical stability, it stands as the ideal choice for withstanding extreme temperatures and resisting chemical corrosion.
In our advanced facility, we manufacture alumina parts with purities ranging from 75% to a remarkable 99.8%. Our ceramic parts boast a dense body achieved through innovative processes like dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications, such as fitting, friction reduction, and insulation enhancement, we offer secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing, ensuring unparalleled quality and performance.
From ceramic tubes to rings, discs, rods, arms, and wire guides, our expansive range of alumina ceramic rings is designed to meet both prototyping and high-volume demands. We are committed to delivering bespoke solutions that perfectly align with your specific requirements.
