Ceramic to Metal Seals

Ceramic to Metal Seals are specialized components that integrate thick film metalized ceramics with various metals. These components are expertly brazed at high temperatures, creating robust seals ideal for applications that demand high reliability.

Ceramic to Metal Seals

Metalized ceramic components are brazed utilizing Silver (Ag), Copper/Silver (Cu/Ag), and Copper/Silver/Indium (Cu/Ag/In) to metal lead frames, tabs and bases. These robust products are ideal for use in high reliability applications in the military, medical, aerospace, automotive and commercial industries. The design of these Ceramic to Metal Seals can be tailored to meet specific customer requirements.
