Metalized ceramic feedthroughs are crucial components for ceramic-to-metal hermetic assemblies for military, aerospece,medical, electronics and high reliable industry devices. These ceramic parts are regularly made from alumina （Al2O3）with optional purities such as 94.4% (pink), 96%(white), 99%(white), 99.5%(ivory) or higher in order to achieve different particular requirements. Since alumina ceramic offer high-temperature resistance, non-conductive, superb mechanical properties, erosion resistance, oxidization resistance and other remarkable thermal characteristics, these properties make the brazed assembly could fit for high-humidity, high-heat, high-voltage, high-current harsh vacuum environments with reliable working conditions.
Our facility manufactures abundant custom-designed metallized ceramic feedthroughs via art-of-state shaping processes, mainly including dry pressing, ceramic injection molding (CIM) and cold isostatic pressing (CIP) with the capability from large-size to small size. In order to build up the adhesion of metallized layer on surface as well as achieve specified fitting needs, machining process will be carried out at green ceramic body stage, or after sintered ceramic parts to obtain more ideal surface quality and more accurate dimensions, refer to as follows for our production capability

Both brazing strength and gas leakage rate after hermetical process are 2 most vital parameters to verfity the quality of metalized ceramics, we control these quality points from both manufacturing processes and inspection, first one is to formulate the metallization paste uniquely to ensure the partical size, the viscosity at house, sencond one has precision measuring equipment to ensure them.
We believe you could find a high-quality products with affordable price, also an amazing solution based on your project.
