Overview
OptiPowder Ni625 (UNS N06625) is a nickel-chromium-molybdenum-niobium alloy engineered for excellent corrosion resistance, high-temperature stability, and strong mechanical performance in extreme environments. It maintains strength across a wide temperature range and resists fatigue, oxidation, and stress corrosion cracking, making it a reliable choice for demanding advanced manufacturing applications.
OptiPowder Ni625 is produced using Continuum’s M2P gas atomization system, a plasma-based process that converts qualified reclaimed metal into high-quality spherical powder in a single step. Powered by green energy and tightly controlled process conditions, this approach reduces the carbon footprint of powder production while delivering consistent chemistry, flowability, and particle morphology from lot to lot.
OptiPowder Ni625 is engineered for high-performance components operating in corrosive and high-temperature environments, including:
Aerospace engine components, exhaust systems, and thermal structures
Marine and subsea hardware exposed to saltwater environments
Chemical processing and waste treatment equipment handling aggressive media
Energy applications requiring creep resistance and thermal stability

Available PSDs & Customization
Additive Manufacturing Process Compatibility Available PSDs & Customization OptiPowder Ni625 is available in multiple particle size distributions, including 0–15 µm, 0–25 µm, 0–45 µm, 15–45 µm, 45–90 µm, 45–106 µm, and HIP-grade material, with custom PSDs and program-based supply available on request.
Morphology
Powder morphology is predominantly spherical with minimal satellites, with no hollow particles, excessive agglomeration, or foreign-object defects visible at ~300× magnification.
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
