SRI Hermetics owns exclusive technology for connector designs which incorporate the use of explosion welding to join dissimilar metals. Explosion welding (EXW) is a solid state process that uses chemical explosives to accelerate one metal into another at high velocity. This high velocity impact creates a welded interface between the two metals. SRI Hermetics uses EXW to produce bonds between metals that cannot necessarily be welded by conventional means such as aluminum to stainless steel, aluminum to titanium or titanium to stainless steel.

This unique metal joining process gives SRIH the capability of creating hermetic connectors that consist of two, or more, dissimilar metals. The competitive practice of creating unreliable seals in less than optimum connector shell materials is eliminated with SRIH’s bi-metal connector shell technology. Making use of a bi-metallic connector shell reserves one metal portion of the shell for hermetically sealing the contacts (stainless steel portion), while the other metal portion, usually the bulk of the connector, is available to meet the customer’s requirements, (typically aluminum or titanium).
