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. 687 is a copper-zinc-aluminum alloy with high resistance to corrosion and erosion; in addition, it has good strength and ductility and can be cold worked and cold formed readily. It is chiefly used in the form of tubes for various types of equipment such as condensers and heat exchangers.
