●Iron-Nickel-Cobalt alloys for hermetic sealing

【Features】

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.

【Applications】

• ・Hard glass sealing
• ・Ceramic package sealing
• ・CRT electron gun electrodes

【Materials】

• ・KV-2
• ・KV-4
• ・KV-6
• ・KV-15
• ・KV-25
• ・KV-30

【Performance characteristics】

KV-2 and KV-6 type alloys have a very similar thermal expansion property to that of hard glass.
