Product Introduction
Product Introduction
Invar 36 alloy powder is a special low‑expansion iron–nickel alloy with an exceptionally low coefficient of thermal expansion. Precise control of carbon and manganese content is critical. Cold working reduces the coefficient of thermal expansion, while heat treatment within a specific temperature range can stabilize it. The material exhibits an extremely low coefficient of thermal expansion between −250°C and +200°C and possesses excellent ductility and toughness.
