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.Carlson Alloy 70 30 Cu Ni is strong and ductile and has excellent cold-forming properties. Malleability approaches that of copper, and the alloy does not work harden rapidly. It is readily weldable by all of the arc processes and by resistance arc welding and can be brazed and soldered. Alloy 70 30 Cu Ni has excellent resistance to corrosion and erosion. Many applications are related to handling seawater.
