The description of alumina ceramic parts
Aluminum oxide (Alumina) has an extensive application due to its versatility and low material cost than other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion.Our factory produces a selection of purity of alumina from 75% to 99.8%, all of the ceramic parts we supplied are with a dense body via dry pressing, hot pressing, ceramic injection molding, and ISO pressing. In order to achieve some special applications for fitting, reducing friction, and increasing the insulation, we provide a series of secondary processes after sintering, covering CNC machining, polishing, glazing, and metalizing.We manufacture a wide range of alumina ceramic rings, including ceramic tubes, ceramic rings, ceramic discs, ceramic rods, ceramic arms, and ceramic wire guides. Whether it's a prototyping case or high volume demand, we believe we can provide you with a desirable solution.
