Chemical Name: Nickel-iron

Chemical Formula: Fe-Ni

• Invar / Nilvar Description:

a) Invar is nickel-iron alloy which has a rate of thermal expansion approximately one-tenth that of carbon steel at temperatures up to 400°F (204°C).

b) It is used for applications where dimensional changes due to temperature variation must be minimized such as Invar is also used in conjunction with high expansion alloys in applications where a motion is desired when the temperature changes such as in bimetallic thermostats and in rod and tube assemblies for temperature regulators.
