NILO ALLOY 42 - UNS: K94100 - DIN 17745 sheets.

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.

Cold working

Cold working is not suitable for this alloy as it tends to distort the coefficients of thermal expansion.


NILO 42 alloy may be annealed at 850 - 1000°C (1560 - 1830°F).


The NILO 42 alloy is used in the following applications:

Semiconductor lead frames in integrated circuits
Bi-metal thermostat strip
Thermostat rods
Ceramic-to-metal seals
Glass-to-metal seals for television tubes, fluorescent lights.
