Material Description:
High nickel, high cobalt iron alloy. A traditional metal-to- glass sealing alloy that offers a low coefficient of thermal expansion (CTE) similar to glass. Provides the hermeticity required for firmly bonding between metal and glass. Frequently used for hermetic enclosures or packages used to protect electronic or optical devices in aerospace, automotive, optical, optoelectronic, and telecommunication industries.
