Special Metals NILO® Alloy 42 Controlled-Expansion Alloy
Categories:	Metal; Superalloy; Iron Base
Material Notes:	Inflection point 370°C. 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 are tube, sheet, strip, and wire. Data provided by the manufacturer, Special Metals.
Key Words:	UNS K94100; ASTM F 30, B 753; DIN 17745; S.E.W. 385; Werkstoff Nr. 1.3917; AFNOR NF A54-301
