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.Bismuth-Tin 58-42 is a bismuth-base eutectic alloy that melts at 281 F (138 C). It has the highest melting point of the bismuth-base alloys commonly used in industry. It provides scientists, engineers and technicians with an easily castable alloy that is ready for use soon after it freezes. It can be recovered easily and recycled into new uses any number of times. Among its many uses are anchoring parts for machining and grinding, filler for tube bending, solder and dies for wax patterns in investment casting.
