INVAR®
INVAR® is a FeNi36 alloy with s a very low coefficient of thermal expansion. The coefficient is of virtually zero at temperatures ranging from cryogenic to ambient. It has a very low coefficient of thermal expansion from -100°C to +200°C).
This is a key alloy in many applications requiring of course a very low CTE but also good workability and weldability.
Imphy research engineers and engineers’ knowledge about FeNi36 and other iron nickel alloys have been published in a book. This is “the Iron Nickel Alloys”, edited by Tec & Doc Lavoisier. It is a registered trademark by Aperam Alloys Imphy.
INVAR® obtains the Physics Nobel Prize 1920 : https://www.nobelprize.org/prizes/physics/1920/summary/
