Nickel Superalloy Powder – Ni625

Nickel Ni625 Metal Powder For Additive Manufacturing


6K Additive Ni625 metal powders for additive manufacturing. Ni625 is Ni-Cr-Mo-Nb solid solution superalloy with high corrosion resistance, high strength, excellent fatigue resistance, and high-temperature stability. Ni625 properties make this alloy application for additive manufacturing interesting for marine and nuclear applications where corrosion is a concern and aerospace and racing car applications where high-temperature stability is required. The poor machinability of Ni625 makes it ideal for additive manufacturing. Ni625 metal powder is available in various sizes for 3D metal additive manufacturing. 

Ni625 metal powder is available in a variety of sizes. 6K Additive is a leading metal powder manufacturer, so we can customize the PSD that you are looking for.
