Product Description

Invar36 Low Expansion Alloy Readily Weldable And Corrosion Resistance


Invar 36 Low Expansion Alloy Rod Readily weldable and Corrosion resistance


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.

Invar Alloy exhibits extremely low expansion around ambient temperatures, making Invar Alloy particularly useful in applications where minimum thermal expansion and high dimensional stability is required, such as in precision instruments like optoelectronic devices, optical and laser benches, electronics, and other kinds of scientific instruments.
