Product Desciption
Description:
NILO Alloy 42 / W. Nr.1.3917 / UNS K94100
Description:
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.
FeNi42 (for example NILO alloy 42), has a nickel content of 42% and α ≈ 5.3 ppm/°C which matches that of silicon and therefore is widely used as lead frame material for electronic components, integrated circuits, etc.
Chemical Composition:
Average Coefficient of Linear Expansion ā/(10-6/K):
20~100ºC:5.6
20~200ºC:4.9
20~300ºC:4.8
20~400ºC:5.9
20~450ºC: 6.9
20~500ºC:7.8
20~600ºC:9.2
Applications:
Alloy 42 has been used for the glass-to-metal seals in electronic tubes, automotive and industrial lamps, transformer and capacitor bushings and other glass-to-metal and ceramic-to-metal applications.
