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.

BELMONT ALLOY 4977 is a high-strength alloy for casting. Its high strength is achieved by solution treating and precipitation (age) hardening. It has good resistance to corrosion. This alloy is the most widely used high-strength beryllium-copper casting alloy; among its many uses are valves, pump components and molds for plastics.
