Whether your design requires glass-to-metal seals or ceramic to metal (Kryoflex®) hermetic seals, SOURIAU PA&E delivers innovative, versatile, and reliable solutions that perform to the highest standards in a wide range of applications and environments.

Ceramic to Metal Seals

SOURIAU PA&E's ceramic to metal seals incorporating the patented Kryoflex® polycrystalline ceramic, were created to replace conventional compression glass and metalized alumina ceramics for superior bonding properties. It is a unique material that relieves stress within itself and eliminates the most common causes of hermetic failure. SOURIAU PA&E's Kryoflex hermetic seals system demonstrates superior electrical performance while withstanding mechanical and thermal stresses far beyond what glass to metal seals can endure. Kryoflex will directly seal into materials such as stainless steel, titanium, and aluminum.

Glass-to-Metal Seals

When required for a specific application, or utilized when a less-expensive manufacturing alternative to our Kryoflex hermetic seal is necessary, SOURIAU PA&E can also seal glass directly into most any iron/nickel alloy. Our Glass-to-Metal sealing capabilities allow for matched sealing, compression sealing, and Hi-Rel (High-Reliability) sealing using special oxidation and requiring higher processing temperatures, can be used, depending upon individual package requirements. SOURIAU PA&E's hermetic glass-to-metal seals meet or exceed MIL-STD-883 and JEDEC Spec 9A.
