Invar 42 Bars are composed primarily of 42% nickel, with iron making up the balance, which endows them with an exceptionally low coefficient of thermal expansion. This alloy can also include small quantities of manganese, carbon, and silicon to enhance stability and workability. Regarding mechanical properties, Invar 42 exhibits moderate tensile strength, good ductility, and outstanding toughness. It preserves dimensional precision even under temperature changes, guaranteeing predictable performance during thermal stress. Such qualities make Invar 42 a dependable option for precision applications requiring minimal expansion and steady performance in controlled settings.
