Invar® Foil

Invar Foil, also known as Invar Alloy Foil or Fe-Ni36 Alloy Foil, is highly regarded for its unique property of having an extremely low coefficient of thermal expansion (CTE). This characteristic makes it an ideal material for applications requiring precise dimensional stability under varying temperatures. Invar Foil is extensively used in the aerospace industry for components such as satellite structures and precision instruments, as well as in the electronics industry for shadow masks and photomasks. The foil’s stability and reliability are further enhanced by its resistance to oxidation and corrosion.
