Few materials in the aerospace industry carry the same reputation as Inconel 718. Recognized by the AFNOR designation NC19FeNb, this fine wire alloy has been engineered to provide strength, corrosion resistance, and stability in extreme conditions. At DLX, we supply Inconel 718 fine wire designed specifically for high-strength aerospace fasteners, ensuring safety and reliability in some of the most demanding applications on the planet.
For more details, pls directly contact us.
Inconel 718 fine wire is a precipitation-hardened nickel-chromium alloy that incorporates iron, niobium, molybdenum, and titanium. Its chemical composition is carefully balanced to deliver high tensile and fatigue strength while maintaining exceptional resistance to both oxidizing and reducing environments. Unlike many alloys, Inconel 718 maintains its mechanical properties across a broad temperature range—from cryogenic conditions to about 700°C.
The fine wire form of Inconel 718 is particularly suited for aerospace fasteners, where precision, consistency, and strength are crucial. Available in spools, coils, or cut lengths, DLX ensures that every batch of wire meets stringent aerospace standards, ready for integration into critical systems.
