What is nickel alloy 718?
Material Note: IN718 was developed in the early 1960s and is still considered the material of choice for most aircraft engine components operating below 1200°F (650°C). Inconel 718 is a precipitation hardenable nickel-chromium alloy that also contains significant amounts of iron, niobium and molybdenum and smaller amounts of aluminum and titanium. It combines corrosion resistance and high strength with excellent weldability including resistance to post-weld cracking. The alloy has excellent creep rupture strength at temperatures of 1300°F (700°C).
Applications: Aerospace, gas turbines, rocket engines, spacecraft, shuttles, nuclear reactors, pumps, turbopump seals and tools.
Forms: round, flat, extruded profiles, tubes, tubes, forgings, plates, sheets, strips and wires.
