Ceramic Hermetic Seal

Our ceramic to metal seals incorporate the patented kryoflex polycrystalline ceramic and are an alternative to conventional compression glass and metallized alumina ceramics.

Ceramic hermetic seal.

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. Elan technology s glass ceramic composites also have higher chemical durability can resist higher temperatures and can be more easily machined to. Choose a metal such as kovar with the most closely matched expansion to the ceramic when possible. The elan 46 ceramic glass composite has unique properties that allow for the ability to vary the coefficient of thermal expansion and can therefore form hermetic seals with a variety of metals.

The metal selected to be bonded to the outside diameter of a ceramic should have a thermal expansion al2o3. Kryoflex is a unique material that relieves stress within itself and eliminates one the most common causes of hermetic failure cracked glass. 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. 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.

Hermetic vacuum sealed ceramaseal products are built to endure extreme conditions. Maximum solid metal pin diameter is 060 where pin is brazed directly to ceramic id. Winchester s ceramic hermetic sealing provides. The ceramic experts for advanced ceramics ballistics protection and total hermetic solutions ceramtec north america is a world leader in ultra high vacuum seal technologies as well as a leading supplier of various advanced ceramic products.

Place ceramic in compression rather than tension. 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. Hermetic epoxy seals also offer the design flexibility of sealing either copper alloy wires or pins instead of the. Hermetic sealing is commonly used to encase electrical mechanisms as well as to contain functional gases.

Ceramaseal hermetically sealed to endure cold heat or high pressure. Complete hermetics is a custom manufacturer of glass to metal ceramic to metal hermetic seals and feedthroughs.
