Description	Alloy 36 (commonly known as Invar) is a nickel-iron alloy containing approximately 36% nickel. It is characterized by an extremely low coefficient of thermal expansion, which significantly suppresses dimensional changes caused by temperature variations. Because of this property, it is widely used in applications requiring high dimensional stability, precision components, and structures where thermal stress must be minimized. Typical applications include semiconductor manufacturing parts, bimetal components, and precision assemblies where thermal stability is critical.
