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.OSTALLOY 117 is a eutectic, controlled-shrinkage alloy that melts at 117 F. It provides the engineer, scientist and technician with easily castable material that is ready for use soon after it freezes. It can be recovered easily and recycled into new uses any number of times. Its low melting temperature and controlled-shrinkage characteristics make it highly useful for such applications as low-temperature solder, proof casting of cavities and dental models.
