Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) distinguishes itself with a compelling array of applications, thanks to its extraordinary versatility and cost-efficiency compared to other advanced ceramics. Renowned for its outstanding electrical insulation properties, high thermal tolerance, exceptional hardness, and superior wear and chemical resistance, Alumina is the material of choice for challenging high-temperature and corrosive environments.
Within our cutting-edge manufacturing facility, we produce alumina parts with purities ranging from a sturdy 75% to a near-flawless 99.8%. Utilizing advanced techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing, we achieve dense and durable ceramic bodies. For bespoke applications requiring enhanced fitting, friction minimization, and superior insulation, we offer a comprehensive range of secondary processes, including precision CNC machining, polishing, high-gloss glazing, and metalizing post-sintering.
Specializing in an extensive variety of alumina ceramic products, we manufacture rings, tubes, discs, rods, arms, and wire guides, supporting everything from prototyping to mass production. Committed to excellence, we deliver solutions perfectly aligned with your unique specifications and requirements.
