Description and applications*
NOVA36 is a binary austenitic nickel-iron low expansion alloy containing 36% nickel. It maintains nearly constant dimensions over the range of normal atmospheric temperatures and has an extremely low coefficient of thermal expansion from about -250°C to about 200°C.
Such an alloy has good fatigue and mechanical properties at cryogenic temperatures. It exhibits moderately high strength along with good ductility and toughness.
Mainly used for applications requiring precise dimensional stability:
• standard of length, measuring devices, laser components, bi-metal thermostat
strips and thermostat rods;
• tooling and dies for aerospace composite tooling,
• cryogenic components and piping;
• liquefied natural gas production and storage equipment;
• marine components;
• wind turbines.
