Useful Properties of Nickel Alloy AMS 5663 at FlightMetals

It's so easy to know the useful properties of nickel alloy AMS 5663 at FlightMetals like corrosion resistance, excellent service temperature range, etc.

Nickel-chromium based super alloy AMS 5663 (sometimes called Inconel 718) is mainly ideal for those aerospace applications which should be manufactured with an metal having the feature of operating on extremely high temperature environments, corrosion, thermal and creep resistance, etc. This amazing alloy is an excellent choice for aerospace industry as it can even cater the toughest aerospace requirements.

AMS 5663 is the super nickel-chromium based alloy that has excellent service temperature range. It can be used permanently on the temperature of above 600°C. It’s Young's modulus is near to the double than of Ti6Al4V (Grade 5 Titanium) and close to that of unalloyed carbon steel (CK45). This nickel alloy owns good rupture and creep strength with high level of resistance to corrosion and fatigue. It properly maintains the strength and hardness over an long period of time at extremely high temperatures. Perfect corrosion resistance is the main reason for considering it ideal for use in high temperature environments.

AMS 5663 (Inconel 718) covers around 50% of the weight of an aircraft’s turbojet engines, being the main component for discs, blades, and casing of high pressure part of discs and compressor as well as few turbine section’s blades. As it has the better hardness at low temperatures that protects it from brittle fracture, it also has few applications in rocket engines and cryogenic environments.

AMS 5663 (Inconel 718) contains large amount of iron which decrease its cost per kilogram while giving it the precipitation hardening effect. In the matrix, iron’s low mobility provides the chief strengthening phase (γ’’), an slow precipitation kinetics that reduce the proneness to post-weld cracking. Inconel 718 is specially designed to defeat the low joinability of this class of materials, usually prone to crevices corrosion.

Few alloying elements give the AMS 5663 an excellent resistance to corrosion on up to 1000°C / 1832°F. For instance, nickel is truly useful in fighting with CLSCC (chloride stress corrosion cracking) and saves from corrosion in various organic and inorganic oxidizing compounds, in the comprehensive range of acidity and alkalinity. Chromium (which is second prime alloying element in this alloy) gives it the ability to fight to the attacks from Sulfur compounds and oxidizing media while component Molybdenum help in making the pitting corrosion resistance better.

Wrapping it Up: Inconel 718 is an great nickel alloy that covers each and almost every aerospace applications’ requirements like better strength and toughness at high temperature, excellent corrosion resistance, etc. You can choose confidently this alloy for manufacturing the aircraft’s crucial parts like turbo jet engines.
