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 255 is a bismuth-base eutectic alloy that melts at the low temperature of 255 F (124 C). After freezing it is characterized by initial shrinkage followed by slow growth. It provides scientists and engineers with an easily castable material that is ready for use practically as soon as it freezes. It can be recovered easily and recycled into new uses any number of times. Among its many uses are (1) Anchoring metal parts in glass, (2) Filler for large diameter tubes for bending, (3) Proof casting forging dies, (4) Fusable elements is safely plugs and (5) Mechanical dentistry.
