OptiPowder C964 (CuNi 70/30)
Continuum OptiPowders are produced by our proprietary Greyhound Melt-to-Powder (M2P) system. This advanced plasma-based atomization process transforms reclaimed aerospace-grade feedstock into high-purity, spherical powder in a single step. By utilizing 100% reclaimed materials and green energy sources, this process significantly reduces environmental impact while delivering consistent flowability and exceptional material performance.
Material Overview
OptiPowder C964 is a high-conductivity copper-nickel (CuNi 70/30) alloy powder engineered for excellent strength, ductility, fabricability, and thermal and electrical conductivity in demanding environments. Its balanced composition provides superior resistance to general corrosion and stress-corrosion cracking in seawater and brackish water, as well as strong performance in high-salinity, high-temperature, and high-velocity turbulent conditions.
Designed for marine, energy, and industrial applications, C964 is well suited for components exposed to aggressive fluid environments, including cooling systems, seawater piping, heat exchangers, and other critical hardware where both durability and conductivity are required. OptiPowder C964 supports additive manufacturing, thermal spray, and other advanced forming technologies that demand reliable, production-grade powder.
