What is Invar 36?

INVAR 36, also known as FeNi36, is a nickel-iron alloy with a low coefficient of expansion, containing 36% nickel. It maintains consistent dimensions across normal atmospheric temperatures and exhibits low expansion from cryogenic temperatures up to approximately 500°F (260°C). This alloy retains strength and toughness even at cryogenic temperatures, making it ideal for various applications such as standards of length, measuring devices, laser components, bi-metal thermostat strips, thermostat rods, and tanks and piping for storing and transporting liquefied gases.

For optimal performance in applications involving a wide temperature range, fully annealed material is recommended. Annealing at 850-900°C (1560-1650°F) for a suitable duration, with slow cooling, is preferred. For devices requiring maximum dimensional stability within normal ambient temperatures, a specific heat treatment process is advised: heating to 830°C (1525°F) for 30 minutes followed by water quenching, then re-heating to 300°C (570°F) for 1 hour with air cooling, and finally re-heating to 100°C (212°F) for 48 hours with air cooling. This treatment ensures full stability at temperatures up to 100°C (212°F). Protective atmospheres should be employed during preheating or annealing processes.
