Introduction
NILO 36 alloy consists of 36% nickel and is capable of maintaining constant dimensions over the range of normal atmospheric temperature.
This alloy has a low coefficient of expansion from cryogenic temperatures up to about 260°C (500°F). NILO 36 retains good toughness at cryogenic temperatures. NILO 36 alloy is available in the form of round, extruded section, plate, strip, tube and wire.
This datasheet will look into the chemical composition, properties and applications of NILO 36 alloy.

Fabrication
Cold working
Cold working is not suitable for this alloy as it tends to distort the coefficients of thermal expansion.
Annealing
NILO 36 alloy may be annealed at 830oC (1525°F) for about 30 min, water quenched and then reheated to 300°C (570°F) for 1 hour. This is followed by water quenching and a final reheating to 100°C (212°F) for 48 hours and then air cooled.
Applications
The NILO 36 alloy is used in the following applications:
-
Making of standard length measurements and measuring devices
-
Cryogenic and laser components
-
Bi-metal strip, thermostats
-
Tanks and pipes that transport liquefied gases
-
Aerospace composites
-
Pendulum and precision components.
