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.COPPER Alloy No. 240 is a copper-zinc alloy having high ductility and malleability combined with good corrosion resistance and relative freedom from intergranular corrosion and embrittlement. It is recommended for pump lines, flexible hose and ornamental work.
