Product Description

 

Ceramic to metal seals are hermetic joints created by fusing ceramic components to metal substrates using a variety of joining techniques. These seals are renowned for their exceptional heat resistance, chemical stability, and mechanical durability. They're able to withstand extreme temperatures and harsh environments, making them ideal for use in high-performance applications.

Brazing Technology is a crucial aspect of the manufacturing process of ceramic to metal seals. 
Brazing involves the use of a filler metal, which has a lower melting point than the base materials, to bond the ceramic and metal components together. This process creates a strong, reliable joint that maintains the integrity of both materials.
