Nilo® 36

A Nickel-Iron, low expansion alloy containing 36% Nickel. It maintains near constant dimensions over the range of normal atmospheric temperatures and has a low coefficient of expansion from cryogenic temperatures to about 500oC (930oF). Nilo 36 also retains good strength and toughness at cryogenic temperatures.

Nilo® 36 is also known as Invar / Invar 36, Supra 36, and Pernifer 36.
