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.

AMBRALOY 687 is a copper-zinc-aluminum-arsenic alloy. It is effectively inhibited against dezincification by the small but strictly regulated addition of arsenic (nominally 0.04%). It is superior to Admiralty Metal (Copper Alloys No. C44300, C44400 and C44500) where water is contaminated by sewage, where velocities are higher than normal, and where impingement is more severe than normal. Typical uses are condenser and heat-exchanger tubes, distiller tubes and ferrules.
