invar 36

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.

Invar 36 (FeNi36) is a nickel-iron, low-expansion alloy that exhibits a near-zero rate of thermal expansion and can maintain almost constant dimensions from cryogenic temperatures to 260°C. Invar 36 can be hot and cold formed and machined using processes similar to austenitic stainless steels.It has become a popular choice for composite material manufacturing.
