    EOS 3D Printing Metal Materials

    IN625, IN718, IN939 and HX
    Nickel Alloys for
    Additive Manufacturing

Nickel alloys material characteristics make it ideal for a wide range of applications, for example in gas turbines for both aerospace and energy industries, process industry, oil and gas, ship building.

The nickel alloy family of powders encompasses the IN625, IN718, IN939 and HX alloys. All these powders are designed and tested for use on EOS’ metal systems.

All EOS nickel alloy powders are shipped with an inspection certificate (according to EN 10204, Type 3.1) showing the results of the extensive QA testing not only of the powder itself, but also of test parts built on a dedicated system with a dedicated process.

EOS also offers a wide range of validated processes for each of the above materials. These offer the optimal combination of parameters (e.g. laser power, layer thickness, etc.) in order to ensure that the properties of the 3D printed part are consistently achieved.

EOS NickelAlloy IN625

Parts are characterized by having high tensile, creep and rupture strength and are heat and corrosion resistant. This combination is ideal for for racing applications, gas turbines in aerospace and energy as well as ship building industries.

EOS NickelAlloy IN939

Parts show high tensile, fatigue, creep and rupture strength at temperatures up to 850°C (1560°F) as well as excellent corrosion and oxidation resistance. Parts are crack-free in as manufactured and heat-treated condition and are resistant to strain-age cracking. A short AM-optimized heat treatment is needed but not HIP. 

Typical Part Properties

Ultimate Tensile Strength  1510 MPa
Yield Strength  1115 MPa
Elongation @ Break 12 %
