Invar 36

UNS #K93600

Invar 36 is a 36% nickel-iron alloy with a rate of thermal expansion approximately one-tenth that of carbon steel at temperatures up to 400°F (204°C). This alloy is used for applications where dimensional changes due to temperature variation must be minimized or in conjunction with high expansion alloys in applications where a motion is desired when the temperature changes.
