Invar 36 Description

Invar 36 is a 36% nickel-iron alloy possessing a rate of thermal expansion approximately

one-tenth  that of carbon steel at temperatures up to 400°F(204°C)

Shape we can provide:  Round bar/plate/strip/wire

 

Invar 36  Application

This alloy has been used for applications where dimensional changes due to temperature variation must be minimized such as in radio and electronic devices, aircraft controls, optical and laser system, etc.Invar 36 alloy has also been 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.
