INDALLOY 281-338 is a tin-base alloy that can be melted easily. It is non-eutectic alloy and melts through a temperature range of 281-338 F. It provides scientists and engineers with an easily castable material that is ready for use soon after it freezes; in addition, it can be recovered readily and recycled into new uses any number of times. Among its many uses are fusible mandrels for electroforming, proof casting in foundries, low-temperature solder, holding jet engine blades for machining and dies for wax patterns for investment casting. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, heat treating, and machining. Filing Code: Sn-10.
