# Continuum releases new high-conductivity CuNi 70/30 powders

[Continuum Powders, a certified metal powder producer](https://www.voxelmatters.directory/company/continuum/), has released two new copper-nickel alloy powders, OptiPowder C715 and OptiPowder C964, engineered for exceptional corrosion resistance, thermal and electrical conductivity, and mechanical stability in harsh operating environments. Produced through Continuum’s proprietary Greyhound Melt-to-Powder (M2P) process, both alloys are manufactured using certified reclaimed feedstock to deliver high-performance powder solutions with significantly reduced environmental impact.

[Developed for demanding marine](https://www.voxelmatters.com/voxelmatters-maritime-am-focus-2025-ebook/), energy, and industrial applications, the new CuNi powders provide outstanding resistance to seawater corrosion, stress-corrosion cracking, and high-velocity erosion. Their balanced compositions and stable mechanical behavior across broad temperature ranges make them well suited for LPBF, EPBF, binder jetting, HIP, and DED platforms, as well as thermal spray and other advanced manufacturing processes.

OptiPowder C715 and OptiPowder C964 are produced using [Continuum’s M2P atomization technology](https://www.voxelmatters.com/continuum-powders-launches-direct-powder-feeder-dpf/), which transforms reclaimed aerospace-grade metal into high-purity, spherical powder with consistent flowability and morphology. As part of the company’s OptiVantage quality framework, each powder undergoes rigorous chemical and physical characterization to support repeatable performance in serial production environments.

By manufacturing these alloys from reclaimed materials and maintaining purity through strict analytical and process controls, Continuum helps manufacturers reduce material waste, strengthen supply chain resilience, and advance measurable sustainability outcomes in metal additive manufacturing.

“Continuum’s primary mission is to provide customers with reliable, high-performance powders,” said Rob Higby, CEO of Continuum Powders. “With the addition of C715 and C964, engineers working in marine, energy, and industrial sectors now have access to copper-nickel powders that combine exceptional corrosion resistance with the consistency required for production-grade additive manufacturing.”

Both powders offer high corrosion resistance in seawater and brackish environments, stable mechanical properties at elevated temperatures, excellent thermal and electrical conductivity, proven weldability and ease of fabrication, and strong resistance to high-velocity erosion containing silt and bubbles.

Continuum offers each alloy in multiple particle size distributions, including 10–45 µm, 15–53 µm, 45–106 µm, and custom cuts tailored to customer platforms and process requirements.

The introduction of C715 and C964 complements Continuum’s process innovations, including its next-generation Direct Powder Feeder, which reclaims unused powder and returns it directly to atomization for reuse. Together, these advancements support a more circular and resilient metal supply chain for advanced manufacturing.
