Invar 36 Alloy (Alloy 36, NiFe36, FeNi36): The Ultimate Low Thermal Expansion Precision Alloy
Also known as: Invar, NILO 36, 1.3912, 4J36, Nickel-Iron 36 Alloy 1. What is Invar 36 Alloy? Invar 36 is a 36% nickel-iron precision alloy renowned for its near-zero coefficient of thermal expansion (CTE). Discovered by Swiss physicist Charles Édouard Guillaume in 1896 (who won the 1920 Nobel Prize in Physics for this breakthrough), Invar […]
