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. C46400 is a classic marine alloy containing nominally 0.8% tin. It has moderate strength and ductility and excellent resistance to corrosion in both salt and fresh water. It is a widely used marine alloy; its many uses include marine hardware, bolts, nuts, propeller shafts, valve stems and condenser plates.
