What is nickel-iron alloy?


Nickel-iron or iron-nickel alloys are a group of alloys consisting mainly of nickel and iron.


The nickel-iron (NiFe) family of alloys 42, 46, 48 and 49 exhibit low thermal expansion properties over a range of temperatures and are ideal for controlled expansion applications.


Adding 42, 46, 48 and 49% nickel to iron reduces the coefficient of thermal expansion, making these alloys suitable for medical applications, electronics, aerospace engineering, telecommunications and cryogenic components.
