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 281-338 is a non-eutectic alloy with a melting range of 281-338 F (138-170 C). It provides scientists, engineers, manufacturers and technicians with an easily castable material that is ready for use soon after it freezes. It has the advantage that it can be recovered easily and used again many times. Among its many uses are proof castings in foundries, lost-wax pattern dies, holding or anchoring parts for machining and fusible mandrels for electroforming.
