Product Overview
AM-IN718-22D is a premium-grade additive manufacturing powders solution engineered for mission-critical metal AM applications. This nickel-based superalloy powder—specifically Inconel 718 powder—meets stringent aerospace and industrial standards, including AMS 7000 and NADCAP qualification. Produced via the high-purity Plasma Rotating Electrode Process (PREP), it delivers exceptional spherical morphology, low oxygen content, and outstanding flowability—key attributes for consistent layer spreading and defect-free part production in laser powder bed fusion (LPBF) and electron beam melting (EBM) systems.
As a purpose-built PREP powder, AM-IN718-22D offers superior consistency over gas-atomized alternatives, with minimized satellite formation and tightly controlled particle size distribution (22–63 μm). Its composition and thermal stability enable exceptional mechanical properties post-heat treatment—including high tensile strength, creep resistance up to 700°C, and excellent corrosion resistance in aggressive environments.
Key Features
