High Current Vacuum Metalized Ceramic Insulator
To achieve the ceramic to metal joining the application, a metal coating will be applied on the specific surface of the ceramic component, then it the ceramic to metal, ceramic to ceramic can be brazed together. We provide different type metallization with metal coating via banding, screen printing, brushing, spraying, like Mo/Mn with nickel plating, Tungsten(W) with gold plating, silver plating.
It's commonly made of alumina oxides with min. 95% purity. This Metallized Ceramic Insulator can be formed via dry pressed, ceramic injection molding and hot pressed. With their exceptional high insulation, anti-high voltage and high current properties, all of them play a very important role in vacuum-based devices.
Besides Metallized Ceramics, we offer other wide of ceramic parts, like Zirconia Ceramic Components , Ceramic Seals, Thermostat Ceramics, Textile Ceramics, various of the Advanced Ceramic Plate and Ceramic Tubes and so on.
