Ceramic Hermetic Seal

Hermetic sealing is the process of creating a container of some sort that is airtight.

Ceramic hermetic seal.

Maximum solid metal pin diameter is 060 where pin is brazed directly to ceramic id. Since ceramax seals are more compatible than glass with high expansion metal alloys including aluminum titanium and stainless steel the customer was able to enjoy the benefits of stainless but have a hermetic seal that can better withstand temperature extremes. That means that any material in the container whether it s a gas liquid or solid will not leak from the container. Hermetic seal products include qualified military connectors high pressure high temperature hpht bulkhead connectors very high temperature connectors and ruggedized connectors that combine glass seals with advanced peek polyetheretherketone molding technology.

Epoxy hermetic seal designs can be used in hermetic seal applications for low or high vacuum or pressures effectively sealing gases or fluids including helium gas to very low helium gas leak rates similar to glass or ceramic. Ceramtec north america pioneered the science of ceramaseal ceramic to metal sealing more than 60 years ago and is still the world leader in ceramic to metal sealing technology today. Our ceramic to metal seals incorporate the patented kryoflex polycrystalline ceramic and are an alternative to conventional compression glass and metallized alumina ceramics. Kryoflex is a unique material that relieves stress within itself and eliminates one the most common causes of hermetic failure cracked glass.

Ceramaseal hermetically sealed to endure cold heat or high pressure. Hermetic epoxy seals also offer the design flexibility of sealing either copper alloy wires or pins instead of the. Elan technology s glass ceramic composites also have higher chemical durability can resist higher temperatures and can be more easily machined to. Complete hermetics is a custom manufacturer of glass to metal ceramic to metal hermetic seals and feedthroughs.

Hermetic sealing is commonly used to encase electrical mechanisms as well as to contain functional gases. Place ceramic in compression rather than tension. Winchester s ceramic hermetic sealing provides. Our team has a wide range of knowledge to design and develop the hermetic connectors hermetic packages hermetic headers vacuum viewports hermetic seals and hermetic feedthroughs to fit your specifications.

Hermetic vacuum sealed ceramaseal products are built to endure extreme conditions. Choose a metal such as kovar with the most closely matched expansion to the ceramic when possible.
