Common Trade Names: Invar 36®, Nilo 6®, Pernifer 6®

Invar 36® is a nickel-iron, low expansion alloy that contains 36% nickel and possesses a rate of thermal expansion approximately one-tenth that of carbon steel. Alloy 36 maintains nearly constant dimensions over the range of normal atmospheric temperatures, and has a low coefficient of expansion from cryogenic temperatures to about 500°F. This nickel iron alloy is tough, versatile and retains good strength at cryogenic temperatures.

UNS K93600 Invar 36 Material Properties 

Invar 36 Alloy is a solid single-phase alloy, that primarily consists of nickel and iron. Nickel Alloy 36 retains good strength and toughness at cryogenic temperatures due to its low coefficient of expansion. It maintains nearly constant dimensions at temperatures below -150°C (-238°F) all the way up to 260°C (500°F) which is critical to cryogenics.

Invar 36® Material Advantages

Invar 36 can be hot and cold formed and machined using processes like austenitic stainless steels and is also weldable using Filler Metal CF26. Some of the other benefits associated with the use of Invar nickel alloy 36 include: 
  • Superior dimensional stability
  • Numerous workability aspects
  • Extremely low coefficient of thermal expansion (CTE)

Invar 36® & Coefficient of Thermal Expansion 

Invar low expansion alloys are widely known and utilized because they exhibit a coefficient of thermal expansion (CTE) that is close to zero. This beneficial quality has made UNS K93600 one of the most effective alloys for the manufacturing of precision instrumentation. Alloy 36 is generally thought of as the metal of choice for any type of low expansion application, because it has a very small CTE.
