View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.90-10 Cupro-nickel is a highly ductile, malleable and corrosion resisting alloy, suitable for water applications. The alloy has approximately 1.4% iron to improve its resistance to sea water. It has good resistance to general corrosion and erosion. Easily fabricated. Readily weldable.
