INCONEL 718 FOR AEROSPACE ADDITIVE MANUFACTURING

3D Printed Turbine Rotor for Aerospace

2

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.

WHAT ARE THE MAIN APPLICATIONS OF INCONEL 718 IN AEROSPACE?

Inconel 718 is used mainly in the manufacture of parts, exposed to extremely high temperatures as:

Turbines Blisks Cases Rings Exhaust Parts

5

WHAT ARE THE MAIN MECHANICAL CHARACTERISTICS OF INCONEL 718?

The main characteristics of Inconel 718 can be summarized as follow:

Best tensile strength, fatigue and creep-rupture properties

Corrosion and oxidation resistance

Great weldability

6

WHY SHOULD THE AEROSPACE ADDITIVE MANUFACTURING USE INCONEL 718?

The aerospace sector is a huge market that requires modern, fast and reliable manufacturing.

Inconel 718 is designed to resist very high temperatures and a wide range of severely corrosive environments, pitting and crevice corrosion.

When laser-sintered Inconel 718 keeps all its best properties and offers a great diversity of complex shapes.
