Product description
Osprey® Cu30Ni is a copper- and nickel-based alloy with excellent corrosion resistance, tensile strength greater than 414 MPa/60 Ksi and ductility typically greater than 20%, over a wide range of temperatures and especially at very low temperatures. Used extensively in marine, defense, industrial, nuclear and petrochemical applications, especially for pipe fittings and valves, condensers and heat exchangers with anti-microbial and anti-algae properties.
This metal powder is manufactured by Inert Gas Atomization (IGA), producing a powder with a spherical morphology which provides good flow characteristics and high packing density. In addition, the powder has a low oxygen content and low impurity levels, resulting in a metallurgically clean product with enhanced mechanical performance.

Powder characteristics and morphology
Powder for Additive Manufacturing
Osprey® metal powder for Additive Manufacturing is characterized by a spherical morphology and high packing density, which confer good flow properties. For powder bed processes these are essential when applying fresh powder layers to the bed to ensure uniform and consistent part build.
For blown powder processes, such as Direct Energy Deposition (DED), good flow ensures uniform build rates. Tight control of the particle size distribution also helps ensure good flowability. Low oxygen powders result in clean microstructures and low inclusion levels in the finished parts.
