Description of Alumina Ceramic Parts
Aluminum oxide (Alumina) provides vast application possibilities due to its incredible adaptability and cost-effectiveness compared to other advanced ceramics. Known for its high electrical insulation resistance and ability to withstand high temperatures, alumina also offers remarkable hardness, wear resistance, and chemical stability, making it a top choice for environments that demand high-temperature endurance and chemical corrosion resistance.
Our factory specializes in producing alumina parts with purity levels ranging from 75% to an impressive 99.8%. Each ceramic part we deliver is manufactured with a dense body through methods such as dry pressing, hot pressing, ceramic injection molding, and ISO pressing. For specialized applications requiring enhanced fitting, friction reduction, and improved insulation, we offer secondary processing post-sintering that includes CNC machining, polishing, glazing, and metalizing.
We expertly manufacture an extensive range of alumina ceramic rings, including tubes, rings, discs, rods, arms, and wire guides. Be it for prototyping or catering to high-volume demands, we pride ourselves on providing solutions tailored to meet your specific requirements.
