EOS has added a new nickel alloy material to its growing and expansive list of metal powders available for use in powder bed additive manufacturing (AM).

The new material, EOS NickelAlloy IN939, is a nickel-chromium alloy that balances strength in high-temperature settings, corrosion and oxidation, fatigue, and creep strength at temperatures up to 850 ℃ (1,560 °F). EOS NickelAlloy IN939 offers greater tensile properties, validation, reliability, and crack-resistance than similar materials currently on the market. Parts produced using EOS NickelAlloy IN939 can also be hardened after being manufactured by applying precipitation-hardening heat treatments.

For processing on the EOS M 290 metal AM platform, all these qualities position EOS NickelAlloy IN939 for use in creating industrial gas turbines, (vanes, blades, heatshields), as well as microturbines, turbochargers, power industry parts and other energy industry applications exposed to high temperatures and extreme elements.

In addition to the immediate availability of EOS NickelAlloy IN939 for the EOS M 290, there is a planned release for the EOS M 400-4 platform in Q2 2021, and other future platforms.
