Meltio Material Datasheet Rev 2.0 Meltio Invar 36 Invar 36 /Alloy 36/1.3990 Invar is a type of nickel-iron alloy that is known for its unique properties, including low coefficient of thermal expansion and high dimensional stability over a wide range of temperatures. These characteristics make it a valuable material in various applications that require precision and stability, such as precision instruments, scientific measuring devices, cryogenics, composite molds and aerospace components.

Meltio Material Datasheet Tomography Computed Tomography Scan of 3D printed sample part in Invar without detectable voids or defects. Resolution of 24 pm per pixel. Meltio Invar 36 Invar 36/Alloy 36/ 1.3990 Micrography The as printed microstructure of Invar is heterogeneous and mostly austenite with nickel dissolving in y-Fe. Relative density as 3D printed Mechanical Properties Results show that specimens printed using Meltio’s wire-laser metal 3D printed process perform at a high level when compared to samples made with conventional manufacturing methods. Testing is carried out in the less favorable...
