Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is distinguished by its extraordinary versatility and cost-efficiency, setting it apart from other advanced ceramics. Its superb electrical insulation resistance, high-temperature endurance, exceptional hardness, wear resistance, and chemical stability make it an ideal choice for enduring high temperatures and resisting chemical corrosion.
Our state-of-the-art facility excels in producing alumina parts with purities from 75% to an impressive 99.8%. Every ceramic part we deliver is crafted with a dense body using advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. To cater to specific application requirements such as seamless fitting, friction reduction, and insulation enhancement, we offer meticulous secondary processes post-sintering, including CNC machining, polishing, glazing, and metalizing.
We skillfully manufacture an extensive range of alumina ceramic components, encompassing ceramic tubes, rings, discs, rods, arms, and wire guides. Whether your needs are for prototyping or large-scale production, we are fully equipped and ready to deliver solutions that effortlessly align with your requirements.
