High Current Vacuum Metalized Ceramic Insulator

To achieve the ceramics to the metals joining application, a metal coating will be applied on the specific surface of the ceramic component, a metal film on ceramic insulator will be formed after high-temperature fire,  afterwards, the ceramic to the metal, the ceramic to the 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.

These metalized ceramic insulator are commonly made from alumina ceramic with min. 95% purity. They are formed via dry pressed,Isostatic pressed , ceramic injection molding or 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.
