Invar® 42 is a nickel-iron, controlled-expansion alloy containing 42 percent nickel. It has a low and nominally constant coefficient of thermal expansion form room temperature to about 570°F (300°C). Invar® 42 is used for semiconductor lead frames in integrated circuits, bi-metal thermostat strip, thermostat rods, for ceramic-to-metal seals with alumina ceramics, and various glass-to-metal seals such as the core of copper-clad wire for sealing into glass envelopes of electric bulbs, radio valves, television tubes and fluorescent lights. Standard product forms are tube, sheet, strip and wire.
