Sheet nickel alloy 718

for the aerospace industry

Alloy 718 is a nickel-chromium-cobalt-molybdenum alloy with exceptional strength and oxidation resistance at high temperatures. The addition of aluminium, titanium, niobium and molybdenum gives the material superior strength. Alloy 718 is a precipitation-hardenable alloy that also offers high creep-stress rupture strength. The corrosion resistance of the alloy is good, with superior resistance to post-weld cracking. Commercial Applications The material is suitable for applications requiring high resistance to creep and stress rupture at elevated temperatures. Typical applications include aerospace engine components, power industry engines, fasteners and oil & gas sector components. Alloy 718 is also non-magnetic and may be used to fabricate complex parts and components.
