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.BERYLCO 10 is a heat treatable, wrought, beryllium-copper alloy having high elastic and endurance strength, high ductility and impact strength, and high electrical and thermal conductivity. Since this material has good formability and machinability when heat treated, it is generally supplied in this condition, requiring no heat treatment by the fabricator.
