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.DYNAVAR is a corrosion resistant, non-magnetic, age-hardening type cobalt-base alloy with good hot and cold working properties. It is characterized principally by its high fatigue resistance, tensile strength, torque values and corrosion resistance.
