Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) is renowned for its diverse applications, thanks to its superior versatility and cost efficiency compared to other advanced ceramics. It excels in electrical insulation, high-temperature resistance, superior hardness, wear resistance, and exceptional chemical stability, making it ideal for demanding high-temperature and corrosive environments.
In our state-of-the-art facility, we manufacture alumina parts with purities from a solid 75% to an almost flawless 99.8%. Utilizing advanced techniques like dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we craft dense ceramic bodies. For applications that demand enhanced fitting, reduced friction, and superior insulation, we offer a range of secondary processes including CNC machining, polishing, glazing, and metalizing post-sintering.
We are experts in producing a wide array of alumina ceramic products-rings, tubes, discs, rods, arms, and wire guides-supporting everything from prototype development to large-scale production. We confidently deliver solutions that are perfectly aligned with your unique requirements.
