Low expansion alloy ASTM F1684 Invar 36

Product Details

LOW EXPANSION ALLOY INVAR 36

Invar (also know as Invar 36, NILO 36, Pernifer 36, and Invar Steel) is a low expansion alloy consisting of 36% Nickel, balance Iron. 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.
