Invar, also known generically as FeNi36 (64FeNi in the US), is a nickel–iron alloy notable for its uniquely low coefficient of thermal expansion (CTE or α). The name Invar comes from the word invariable, referring to its relative lack of expansion or contraction with temperature changes.
Common grades of Invar have a coefficient of thermal expansion (denoted α, and measured between 20 °C and 100 °C) of about 1.2 × 10−6 K−1 (1.2 ppm/°C), while ordinary steels have values of around 11–15 ppm. Extra-pure grades (<0.1% Co) can readily produce values as low as 0.62–0.65 ppm/°C. Some formulations display negative thermal expansion (NTE) characteristics. Though it displays high dimensional stability over a range of temperatures, it does have a propensity to creep.
Alloy 36 (NILO 36, INVAR 36) is a Nickel-Iron, low expansion alloy which contains 36% Nickel. Invar 36 has a low coefficient of expansion from cryogenic temperatures to about +500°F (260°C). Invar 36 also retains good strength and toughness at cryogenic temperatures. Common applications include tooling for aerospace composites, standards of length, measuring devices, thermostat rods, laser components and tanks and piping for the storage and transportation of liquefied gases.
