> Iron-Nickel-Cobalt alloys for hermetic sealing
The thermal expansion property of this alloy agrees across a wide temperature range with that of hard glass and ceramics, enabling successful hermetic sealing with those materials.
It produces less gas emissions and is highly workable.
KV-2 and KV-6 type alloys have a thermal expansion property very similar to that of hard glass.
