Description of Alumina Ceramic Parts
Alumina ceramic, revered for its multifaceted applications, offers a cost-effective alternative without compromising performance. Its high electrical insulation, robust resistance to high temperatures, exceptional hardness, and durability against wear and chemical stability make it the material of choice for withstanding demanding environments.
Our state-of-the-art facility excels in producing alumina parts with a purity spectrum of 75% to 99.8%. Utilizing advanced forming techniques such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing, our ceramics gain a dense, durable build. Enhanced performance through secondary processes like CNC machining, polishing, glazing, and metalizing is available, ensuring the parts meet specialized operational demands in friction reduction and insulation.
We proudly offer an extensive range of alumina ceramic components, from tubes and rings to discs, rods, arms, and wire guides. Whether the project requires prototyping or large-scale production, we ensure precision-engineered solutions tailored to your specifications.
