SRI Hermetics uses an advanced ceramic dielectric material known as Ceramax as its primary sealing insulator.  Ceramax is a phase changing compound that provides superior hermetic reliability and outstanding electrical performance with an operational temperature range of -269C to +450C.   Ceramax seals are compatible with high expansion metal alloys giving SRI Hermetics the ability to seal copper alloy contacts into connector shell materials not possible with competing technologies.  Aluminum, titanium and high expansion stainless steel alloys are just a few of the shell materials available to choose from.    

Although our Ceramax technology offers many advantages over standard sealing methods there are still applications where glass is a better suited dielectric.  Glass feedthroughs are particularly useful for high frequency match impedance connectors due to the crystalline amorphous properties of the glass which promote low loss signal transmissions.

SRI Hermetics has a full line of laser weldable RF connectors that utilize glass as their dielectric and although glass seals have a reputation for hermetic failure they become very reliable when the design of the feedthrough permits the glass to remain in a neutral stress condition.  All of our laser weldable RF feedthroughs possess this feature and are immune to failure caused by stress such as thermal cyclic fatigue.
