AMS 5701 / UNS N09706 / Inconel 706 Alloy
Inconel 706 (UNS N09706 / AMS 5701)
– High-Strength Nickel Alloy for Aerospace & Turbine Applications
Inconel 706 (UNS N09706) is a precipitation-hardenable nickel-iron-chromium superalloy that combines exceptional mechanical strength with superior fabricability. Developed as a more workable alternative to Inconel 718, this alloy is widely used in aerospace gas turbines, land-based power generation systems, and high-stress structural components.
Certified under AMS 5701 for bars, forgings, and flash-welded rings, Inconel 706 delivers:
High tensile & creep resistance at elevated temperatures
Excellent weldability & formability vs. similar superalloys
Optimized for gas turbine discs, shafts, and casings
