Nickel Inconel 718 AMS 5832

AMS 5832 is the aerospace material specification for Inconel 718 (UNS N07718) welding wire, the nickel filler metal used to join and repair 718 related nickel-alloy components. Inconel 718 is an age-hardenable nickel-chromium superalloy known for high strength and excellent corrosion and oxidation resistance from cryogenic temperatures up to about 1300°F (704°C).

Unlike the bar, sheet and tubing specifications, AMS 5832 covers a consumable filler wire rather than a finished structural product. It’s the specification behind “Nickel Filler Metal 718,” supplied for gas tungsten-arc (GTAW/TIG) and gas metal-arc (GMAW/MIG) welding. A major reason Inconel 718 is favored for fabricated assemblies is its weldability: joints made with AMS 5832 filler are notably resistant to post-weld strain-age cracking, achieving welding efficiency of approximately 100% with the GTAW process, and the weldment can be age-hardened along with the parent metal.

Typical uses include welding Inconel 718 aerospace and gas-turbine assemblies, joining dissimilar nickel alloys, and weld overlay, build-up and repair of high-temperature components.
