OptiPowder Ni718
Continuum OptiPowders are produced by our proprietary M2P Gas Atomization System. This advanced plasma-based process transforms reclaimed metal revert streams into high-quality spherical powder in a single step. By utilizing 100% reclaimed feedstock and green energy sources, this process significantly reduces the carbon footprint while delivering exceptional material performance and flowability.
Material Overview
Ni718 is a nickel-chromium-molybdenum-niobium precipitation-hardened superalloy known for excellent machinability in the solution-annealed state and outstanding strength after heat treatment. It offers sustained high-temperature strength, stress rupture resistance, cryogenic stability, and oxidation resistance, making it a workhorse alloy for demanding environments.
OptiPowder Ni718 is engineered for advanced manufacturing applications requiring high-temperature resistance up to approximately 1,200°C (2,200°F). It is widely used in aerospace, power generation, automotive, oil & gas, and emerging energy systems for components such as turbine blades, hot-section hardware, rocket motors, combustion chambers, and other stress-critical parts.
Key Benefits of OptiPowder Ni718
- High-Temperature Strength & Stability: Maintains mechanical integrity under extreme thermal and mechanical loads
- Excellent Oxidation & Corrosion Resistance: Performs reliably in aggressive hot gas and corrosive environments
- Strong Creep & Fatigue Resistance: Supports long service life in stress-critical and cyclic loading applications
- Designed for Additive Manufacturing: Optimized for LPBF and compatible with EBM and binder jetting workflows
- Sustainability Focused: Produced from reclaimed high-value scrap using green energy to reduce environmental impact
Available PSDs & Customization
OptiPowder Ni718 is available in multiple particle size distributions tailored for Laser Powder Bed Fusion (LPBF), with additional PSD options offered for Electron Beam Melting (EBM), Binder Jetting, and other advanced manufacturing processes. Custom cuts and application-specific PSDs are available upon request to match customer platforms and process requirements.
OptiPowder Ni718 is engineered for high-temperature, high-reliability components, including:
Aerospace turbine blades, vanes, rocket motors, and combustion hardware.
Power-generation and industrial gas-turbine hot-section components.
Oil and gas parts exposed to aggressive, corrosive media.
Energy and fuel-cell structures where stability from cryogenic to elevated temperatures is required.

Additive Manufacturing Process Compatibility
OptiPowder Ni718 supports a wide range of advanced-manufacturing processes, including:
Laser Powder Bed Fusion (LPBF):
complex, high-precision geometries with excellent mechanical properties
Binder Jetting (MBJ):
cost-effective production of larger parts at lower density prior to consolidation
Hot Isostatic Pressing (HIP):
full-density consolidation, defect reduction, & property enhancement for additively manufactured or near-net-shape parts
Electron Beam Melting (EBM):
large, heavily loaded structures requiring high strength
DED and other Advanced Routes
where controlled PSD and chemistry are critical
Available PSDs & Customization
OptiPowder Ni718 is available in multiple particle size distributions tailored to specific platforms and processes (for example, 15–45 µm and 15–53 µm for LPBF/EBM, and coarser cuts for binder jetting or HIP). Custom PSDs, blends, and program-based supply arrangements are available on request to support unique process windows or qualification requirements.
Figure 1
Morphology
Powder morphology is predominantly spherical with minimal satellites, with no hollow particles, excessive agglomeration, or foreign-object defects visible at ~300× magnification, as illustrated in Figure 1.
Blending
Multiple heats may be blended into a single lot when each heat independently meets all chemical and PSD requirements.
Certification
Each shipment includes a certificate of analysis reporting chemical composition, particle size distribution, and any additional agreed-upon test results demonstrating conformance to specifications.
