OptiPowder NiCu 400
PSDs Available:

Material Overview
OptiPowder NiCu 400 is a solid-solution nickel-copper alloy powder combining high strength, toughness, and excellent resistance to a wide range of corrosive environments. Comparable in strength to structural steel, this alloy provides superior durability in both sub-zero and elevated temperatures without undergoing ductile-to-brittle transition.
Continuum produces OptiPowder NiCu 400 using the Greyhound Melt-to-Powder (M2P) platform. By transforming reclaimed high-nickel feedstock into high-purity powder, Continuum delivers a reliable, sustainable alternative to virgin material—optimized for metal additive manufacturing, spray coatings, and traditional forming applications.
Key Benefits of OptiPowder NiCu 400
- Exceptional Corrosion Resistance – Proven performance in marine, chemical, and brine environments.
- High Strength and Toughness – Comparable to steel, with excellent low-temperature ductility.
- Thermal and Electrical Conductivity – Retains physical properties across broad operating ranges.
- Excellent Fabrication Flexibility – Readily machined, welded, or cold worked; suitable for AM and traditional routes.
- Sustainable Feedstock Assurance – Produced from reclaimed nickel-copper alloys within Continuum’s OptiVantage quality framework.
