Web13 nov. 2024 · So, what exactly is Invar? Well, generically, it is known as "FeNi36" or, in the US, "64FeNi." In other words, it is a nickel-iron alloy, with a uniquely low coefficient of thermal expansion. It is described as being a "single-phase" alloy because it is a solid solution consisting of about 36% nickel and 64% iron. WebBeing tough and ductile, Invar is somewhat difficult to machine. Most machinists would agree that Invar is more difficult to machine than steel. Some smaller machine shops may even shy away from certain Invar jobs if the parts are too complex, tightly toleranced or require large amounts of material removal.
