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. This combination delivers a low thermal expansion rate, making it highly suitable for applications where maintaining dimensional integrity is critical despite temperature changes. Alloy 42 round bars and rods come in a range of diameters and lengths, suitable for turning and milling into custom parts. These components are vital for applications such as mechanical linkages,structural components, and various fittings that must resist thermal distortion.
