Invar 36 is a low expansion nickel-iron alloy that contains 36% Nickel. Invar 36 has a thermal rate of expansion approx 1/10 of Carbon Steel at temps above 400°F. Invar 36 is used in electronic and radio devices where one must keep dimensional changes to a minimum.

Invar 36 is available in round bar, sheet, plate and strip. Invar 36 can be machined under similar processes to austenitic stainless steels.
