Invar 36 Bars consist of about 36% nickel and the rest iron, creating an alloy with an incredibly low coefficient of thermal expansion. This distinctive composition enables the material to maintain its dimensional stability across a broad temperature range. On the mechanical side, Invar 36 boasts good toughness, moderate tensile strength, and excellent fatigue resistance. It performs reliably in cryogenic settings and remains stable during thermal cycling. The alloy’s blend of low expansion, durability, and structural integrity makes it ideal for precision components that need to stay accurate under varying temperature conditions.
