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. Available in strips and coils, Alloy 49 is utilized in applications requiring flexibility and continuous material. These forms are valuable in the manufacture of components like springs, connectors, and precision instruments where both flexibility and low thermal expansion are necessary. They are commonly used in sectors like automotive, electronics, and precision engineering.
