Invar 36 is a Nickel-Iron, low expansion alloy containing 36% Nickel, belongs to one of the controlled expansion alloys with the lowest thermal expansion coefficient of any of the iron-nickel alloys. It is widely used in the electronics industry such as radios, thermostats, glass-to-metal seals and structural components in laser systems.
