inconel 718 for aerospace additive manufacturing
3D Printed Turbine Rotor for Aerospace
What is Inconel 718?
Inconel 718 is a nickel-based superalloy. Superalloys possess excellent mechanical strength and are widely used in
extreme environments. It contains chromium (Cr), molybdenum (Mo) and niobium (No), which
improves strength and ductility without heat treatment. It is a gamma prime superalloy.
