Alloy 42, commonly known as Invar 42, is a nickel-iron alloy that exhibits a very low coefficient of thermal expansion, slightly higher than Alloy 36 but still notable for precision applications. Alloy 42 is recognized under various designations and standards, including NILO 42, UNS K94100, DIN 1.3917, FE-NI42, 42N, W.NR. 1.3917, and DILATON 42. These designations underscore its international acceptance and adherence to diverse industry specifications. The alloy is composed of about 42% nickel, with the balance being predominantly iron. Available in flexible strips and coils, Alloy 42 is utilized for applications that require materials to be bent, formed, or used continuously. These products are particularly valuable in the manufacture of springs, connectors, and other components where both flexibility and dimensional stability are required. They find application in automotive, electronics, and high-precision machinery.
