Inconel 718 Powder
Spherical nickel superalloy powder, the most widely used high-temperature AM material.
Material overview
The Metal & Thermal Spray Powders catalog describes Inconel 718 Powder as follows: Spherical nickel superalloy powder, the most widely used high-temperature AM material. Reviewers should evaluate High sphericity and low oxygen and age hardens to high strength. The grade record lists Industrial gas-turbine parts, high-temp tooling, and repair and AM among typical applications. The dataset currently includes 11 property records covering chemical composition, physical properties, and mechanical properties. Standards and form records reference B637 and Powder. Final supply conditions remain subject to specification, inspection, and export-control review.
