What is Invar 42 Bar and Rods?

Invar 42 Bar and Rod are primarily composed of about 42% nickel, with the rest being iron, along with trace amounts of carbon, manganese, silicon, sulfur, and phosphorus. This unique blend results in extremely low thermal expansion and remarkable dimensional stability. The alloy boasts good tensile strength, moderate hardness, and reliable ductility, making it ideal for forming and machining. It maintains accuracy even under thermal stress and performs consistently across varying temperatures, making it perfect for precision-engineered applications.
