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.INDALLOY 281 is a bismuth-base eutectic alloy; it has a melting temperature of 281 F (138 C). This is the highest melting point of the bismuth alloys commonly used in industry. Indalloy 281 furnishes 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 many times. Among its many uses are anchoring parts for machining, foundry patterns and liquid seals.
