Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) stands as a monument of versatility, renowned for its cost-effectiveness when compared to other advanced ceramics. Alumina excels with its high electrical insulation resistance, its fortitude against high temperatures, robust hardness, unparalleled wear resistance, and unwavering chemical stability, making it the quintessential choice for environments demanding resilience against extreme temperatures and chemical corrosives.
Our factory specializes in producing alumina parts with an impressive purity range between 75% and 99.8%. Every ceramic component is crafted to perfection, utilizing advanced methods such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing to achieve a dense and durable form. For specialized applications such as fitting, friction reduction, and insulation enhancement, we apply secondary processes post-sintering, including precision CNC machining, exquisite polishing, elegant glazing, and state-of-the-art metalizing.
We proudly manufacture an extensive variety of alumina ceramic items, from tubes, rings, discs, rods, arms, to wire guides. Whether your project is at the prototyping stage or requires high-volume production, we possess the capability and expertise to deliver solutions that are meticulously tailored to your specifications and requirements.
