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. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on forming, heat treating, machining, and joining. Filing Code: Sn-11. Producer or source: Arconium Corporation of America, A.J Oster Company.
