Alumina Ceramic Water Valve with Good Wear Resistance/Innovacera

Brief introduction of Alumina ceamic
 Alumina or aluminum oxide (Al2O3) in its various levels of purity is used more often than any other advanced ceramic material. CeramTec offers a wide range of material types with different property profiles that can be adjusted via a targeted matrix design.
For Alumina components, we can control tight tolerance. The surface can be polised very well according to customers' requirement. And we accept various designs.
