Alloy 42 / Nilo 42

A nickel-iron controlled-expansion alloy containing 42% nickel. I has a low and normally constant coefficient of thermal expansion from room temperature to about 570F (300C). Used for semiconductor lead frames in integrated circuits, bi-metal thermostats 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.

Available in: Tube, Sheet, Strip and Wire.
