Invar36 for optoeletronics and sensor systems

You know the Invar effect ❓ The relative lack of expansion with temperature changes was even awarded with the Nobel prize in 1920 🏆 MaterialsMonday

The Iron Nickel Alloy Invar 36 / FeNi36 / 1.3912 is currently equipped on one of our MetalAM LPBF systems at Rosswag Engineering for the production of radio telescope parts 📡

Case study coming soon ⏳

The iron-based alloy with 36 wt.-% nickel has a very low coefficient of thermal expansion of up to 250 °C. In addition, the material Invar 36® has a high toughness and ductility. The low thermal expansion leads to a wide range of application possibilities, for example in the field of measuring instruments or in the optoelectronic industry.
