Product Description

Custom High Brazing Strength Glazed 95% Alumina Metalized Vacuum Ceramic Insulator
 

Product Description

 We manufacturer a wide range of customized metallized ceramics for our clients. From pressed ceramics for your packages to producing a part of hermetically sealed assemblies. With the state of the art metallization process and veteran experience, we offer a selection of metallization type to meet special needs from different customers.

The types of metallization:
1. Alumina ceramic base +  silver (Ag) plating directly
2. Alumina ceramic base +  molybdenum (Mo/Mn) metallization
3. Alumina ceramic base +  molybdenum (Mo/Mn) metallization + nickel (Ni) plating
4. Alumina ceramic base + tungsten (W) metallization + gold (Au) plating 


All these metallized ceramic insulators from pressing to metallizing, to packaging are in the processing under highest standards. Every piece out of every batch pass through strictly inspection.
