Kovar Column
Introduction:
Kovar column is precisely manufactured from an iron-nickel-cobalt alloy material. Its thermal expansion coefficient (CTE) is highly compatible with that of alumina, aluminum nitride ceramics, and borosilicate glass. This product is specifically designed for high-reliability gas sealing processes, aiming to effectively alleviate the long-term dimensional drift caused by thermal mismatch of different materials, and to provide a durable and stable physical and chemical protective barrier for internal sensitive electronic components.

Advantages
Material CTE closely matches ceramic/glass packages, effectively avoiding interfacial shear stress concentration in thermal cycling.
02
Excellent hermetic sealing
With glass and ceramic sealing processes it delivers excellent hermeticity against moisture, corrosive gases and particulates.
03
Long-term dimensional Stability
Under high temperature and wide thermal ranges, intrinsic deformation is minimal, ensuring long-term geometric consistency.
04
Excellent environmental durability
Good high-temperature and corrosion resistance for harsh storage and operating environments.
