Alloy 48, also known as Invar 48, is a nickel-iron alloy distinguished by its very low coefficient of thermal expansion, slightly higher than that of Alloy 42 but still notable for precision applications. Alloy 48 is recognized under various designations and standards, including NILO 48, UNS K94800, DIN 1.3922, FE-NI48, A48, and W.NR. 1.3922. These designations reflect its broad acceptance and compliance with diverse industry standards. This alloy typically contains about 48% nickel with the remainder primarily being iron. The specific combination of these elements provides a very low thermal expansion rate, making it ideal for applications where precise dimensional stability is required despite temperature variations. Alloy 48 round bars and rods come in a range of diameters and lengths. These components are important for mechanical linkages, structural elements, and various fittings that must maintain dimensional integrity despite temperature changes.
