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
