Inconel 718® Precipitation Hardenable Nickel Alloy

Common Trade Names: Inconel 718®, Nicrofer® 5219, Alvac® 718, Haynes® 718, Altemp® 718

Inconel 718 is a precipitation hardenable nickel-based alloy designed to display exceptionally high yield, tensile and creep-rupture properties at temperatures up to 1300°F (704°C). The age-hardening response of Inconel 718 permits annealing and welding without spontaneous hardening during heating and cooling. Nickel Alloy 718 has excellent weldability when compared to the nickel-base super alloys hardened by aluminum and titanium. Nickel Alloy 718 is used in aircraft engine parts and high-speed airframe parts such as wheels, buckets, spacers, and high temperature bolts and fasteners.

Inconel 718® Applications

Nickel alloy Inconel 718® has many different industrial applications, some of which include:
  • Jet engine components
  • Gas turbines
  • Aerospace
  • Plastic injection molded tools

Inconel 718® Available Formats

Magellan Metals offers nickel alloy Inconel 718® in a variety of forms, including: 

Nickel alloy Inconel 718® is usually provided in the solution annealed condition (AMS 5662 & AMS 5596), but can be also be supplied in the aged hardened or precipitation heat treated condition (AMS 5663 & AMS 5597) prior to forming.
Inconel 718® strip is available from .001" to .063" in 12" wide coils. 24" wide strip is available in some gauges. Minimum production quantities may apply.
Inconel 718® sheet is available from .012 - .156" thickness in 36" & 48" wide sheets.
Inconel 718® plate is available from .1875" thick to 4"
Inconel 718® tube is available in seamless and welded construction. Standard tube sizes are available, but we also can have small diameter tubes fabricated or re-drawn with close tolerances in small production runs.
While nickel alloy Inconel 718® pipe is generally not available from stock in many cases we can have pipe sizes fabricated, machined or drawn to order.
