产品描述
A nickel-iron controlled-expansion alloy containing 42% nickel. It has a low and nominally constant coefficient of thermal expansion from room temperature to about 570°F (300°C). 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
Strip, plate and wire.
