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. 865 is a copper-zinc-aluminum-iron-manganese alloy that is classified as high-strength yellow brass. It has a tensile strength about 20,000 psi greater than that of the corresponding copper-zinc (yellow brass) alloy; however, it is around the low-strength end of the manganese bronzes. Copper Alloy No. 865 has an excellent combination of strength and ductility and good corrosion resistance. Its many uses include gears, propellers and marine hardware.
