Alloy 49, also known as Invar 49, is a nickel-iron alloy characterized by its low coefficient of thermal expansion. While its expansion rate is slightly higher than Alloy 48, it is still highly suitable for precision applications where minimal thermal distortion is crucial. Alloy 49 is recognized under various designations, including NILO 49, UNS K94890, DIN 1.3912, and A49. These designations indicate its adherence to international standards and specifications. The alloy is composed of approximately 49% nickel and the remainder is iron. This composition results in very low thermal expansion, making Alloy 49 ideal for environments where precise dimensional stability is required despite changes in temperature. Alloy 49 round bars and rods come in various diameters and lengths. These components are essential for applications requiring high accuracy and minimal thermal expansion, such as precision mechanical assemblies and structural components used in demanding environments.
