Alloy 36 (Invar®) / K93603 / ASTM F1684 Widely known under several trades names such as Invar®* and Nilo 36**, this grade is a 36% nickel-iron alloy. It exhibits a near zero rate of thermal expansion from around –100oC up to 200oC. This is around a tenth of the expansion rate of carbon steels. Alloy 36 also demonstrates a high retention of strength and toughness at cryogenic temperatures, making it suitable for a variety of low temperature or low expansion applications. The alloy is ideally suited to areas where dimensional changes due to temperature must be minimal, such as tooling for aerospace composites, radio and electronic devices and structural members in precision equipment such as lasers, measuring devices, thermostats and cryogenic instrumentation. Alloy 36 can also be utilised in combination with a high expansion material to crate mechanical movement with temperature in thermomechanical controls and switchgear.
