Invar 36 Bars are made up of roughly 36% nickel with iron making up the remainder, forming an alloy that has an exceptionally low coefficient of thermal expansion. This unique makeup allows the material to hold its dimensional stability over a wide range of temperatures. From a mechanical standpoint, Invar 36 offers good toughness, moderate tensile strength, and outstanding fatigue resistance. It works dependably in cryogenic environments and stays stable throughout thermal cycling. The alloy’s combination of low expansion, durability, and structural integrity makes it perfect for precision parts that must remain accurate under changing temperature conditions.
