Invar 42 Bars mainly consist of 42% nickel, with the remainder being iron, which gives them a remarkably low coefficient of thermal expansion. This alloy may also contain trace amounts of manganese, carbon, and silicon to improve stability and processing features. In terms of mechanical properties, Invar 42 shows moderate tensile strength, good ductility, and excellent toughness. It maintains dimensional accuracy even with temperature fluctuations, ensuring predictable behavior under thermal stress. These characteristics make Invar 42 a reliable choice for precision applications that demand minimal expansion and consistent performance in controlled environments.
