Lork Group stocks and supplies a wide range of Invar 36 materials, including Invar 36 Bar, Rod, Tube, Cold-Rolled Sheet, Hot-Rolled Plate, and Welding Wire.

 

Invar 36 is a Nickel-Iron, low-expansion alloy containing 36% Nickel. Its coefficient of expansion from cryogenic temperatures to about +500°F (260°C) is low, and it retains good strength and toughness at cryogenic temperatures.

 

Invar 36 material's common applications include tooling for aerospace composites, standards of length, measuring devices, thermostat rods, laser components, and tanks and piping for storing and transporting liquefied gases.
