Invar 36 is a nickel–iron alloy containing approximately 36% nickel and the balance iron, with trace amounts of carbon and manganese. This unique composition gives it an extremely low coefficient of thermal expansion. Mechanically, Invar 36 Bars offer moderate tensile strength, good toughness, and excellent machinability. The material maintains dimensional accuracy over a wide temperature range, making it ideal for precision components. Its stable structure ensures minimal distortion, even under fluctuating thermal conditions.
