GENERAL INFORMATION
Alloy Nifer®36 – the nickel-iron alloy with small coefficient of thermal expansion containing 36% of nickel. Alloy is ferromagnetic at a temperature is lower than Curie's temperature and non-magnetic at higher temperatures. It is used for length standards, measuring devices, laser machines details, stabilizers of thermocouple temperatures, tanks and pipelines for transportation and storage of liquefied gases.
Alloy Nifer®36 is characterized by:
- extremely low coefficient of thermal expansion in the range of temperatures from -250оС to +200оС;
- good ductility, toughness;
- good mechanical properties and small tendency to destruction at cryogenic temperatures.
