Product Description

Invar 36 Controlled Expansion Alloy Foil Thickness Range 0.005-0.05mm



Invar 36 is a Nickel-Iron, low expansion alloy containing 36% Nickel. It maintains nearly constant dimensions over the range of normal atmospheric temperatures and has a low coefficient of expansion from cryogenic temperatures to about +500°C. Invar 36 also retains good strength and toughness at cryogenic temperatures.


Applications include standards of length, thermostat rods, laser components and tanks and piping for
the storage and transportation of liquefied gasses


Invar 36 light gauge foli of thickness 0.005~0.05mm is produced by electrochemical deposition formation process. 



Magnetic properties is better than cold rolled foil

Magnetic properties is equal to Amorphous strip

Mechanical properties is better than Amorphous strip
