Invar36® is a 36% nickel-iron alloy that has a rate of thermal
expansion approximately 1/10 that of carbon steel up to 200° C. It is
typically used in applications where dimensional changes due to
temperature must be minimal such as radio and electronics, aircraft
controls and laser systems, etc. It has also been used in combination with
high expansion alloys where motion is desired during temperature changes
for bimetallic thermostats and temperature regulators.
