A nickel-iron-cobalt
controlled-expansion alloy containing 29% nickel. Its coefficient of expansion,
which decreases with rising temperature to the inflection point, matches the
expansion rate of borosilicate glasses and alumina ceramics.
Used for glass-to-metal seals in
applications requiring high reliability or resistance to thermal shock. Examples
are high-power transmitting valves, transistor leads and headers,
integrated-circuit lead frames, and photography flash bulbs.
