Metallized Ceramics

For over 15 years, we have focused on producing high alumina, zirconia, and aluminum nitride Metallized Ceramics, which enables us to meet various customized needs. These advanced Ceramic Components are ideal for diverse ultra-high vacuum, high frequency, high voltage, high current, and high-pressure applications.
 
Ceramic Metallization makes the specific surface of the ceramic offer both metal and ceramic characteristics simultaneously. Therefore, the ceramic can be connected to metal smoothly by brazing. We supply typical Mo/Mn covering with nickel coating and various other types of metallization, such as Mo/Mn following with silver coating, W plus gold coating, or burning silver on the ceramic surface directly. We can be customized according to the client’s specifications.
 
Metalized Ceramics' reliability and dimensional accuracy are equally crucial in practical applications; either out of specifications may fail the entire vacuum device. To ensure that metalized ceramic components can perform their functions well, both the metalizing and fitting areas of the ceramic body will be precision machined to ensure tight tolerances; after metallization, each batch of products will be tested for weldability, brazing strength, and hermetic according to higher-than-industry standards.
 
With our comprehensive production capacity, we can quickly complete prototyping and realize high-volume mass production. We believe you can find exceptional solutions here if you are looking for metalized ceramics used in the medical, electrical, electronics, and power and sensor industries.
